% \begin{abstract}
%  \noindent A package to manage the margin notes, figures, tables and captions.
%  Also body text can be extended into the margin for wide figures, tables and equation.
%  Twoside symmetry is preserved. For biblatex users, routines for side references are
%  included.
% \end{abstract}
%
% \paragraph*{Note:} Margin notes, figures and tables placements require up to
%  three compilations to be as intended.
%%
% \paragraph*{Note:} This package is inspired by the package |sidenotes| authored by
% Andy Thomas and has many features in common. But, compatibility is
% not maintained between the two.
%
% \section{Usage}
% \subsection{Package options}
% Below the options that can be passed to the package |sidenotesplus|
% with the package defaults listed first.
%
% ~
%
% \begin{tabularx}{\textwidth}{ r X }
%  |mark=| &amp; |alph, Alph, arabic, roman, Roman, fnsymbol| \\
%  |font=| &amp; |rm, sf|\\
%  |size=| &amp; |footnote, normal, small, script| \\
%  |shape=| &amp; | up, it, sl|\\
%  |ragged| &amp; switches to ragged outer margins\\
%  |Ragged| &amp; switches to ragged outer margins but uses ragged2e package\\
%  |classic| &amp; switches to a classic look\\
%  |sepdiff=| &amp; |1em|, or a valid length within reason \\
%  |alerton| &amp; switches on the rendering of the margin alerts \\
%  |per=| &amp; |page, section, chapter, none| defaults to counter per page  \\
% \end{tabularx}
%
% ~
%
% The normal page style is that margin notes are left-right justified with the
% last line ragged to the outer edge. The option |ragged| or |Ragged| changes this
% style to ragged-outer, that is the left page's marginal notes are |\raggedleft|
% and the right page's are |\raggedright|.
% If you opt to use |Ragged| the package |ragged2e| is loaded and |RaggedLeft/Right|
% is used instead of |raggedleft/right|. Load package |ragged2e| with required
% options before |sidenotesplus| is loaded, otherwise |sidenotesplus| loads
% |ragged2e| without any options.
%
% The marginal note's reference number or mark is placed in the margin separator,
% that is on the left page the mark is on the right hand side of the note.
% The option |classic| always places the mark to the left of the marginal note.
% This requires that the margin separator on the left page is slightly reduced if not
% enough space is available to the page outer edge.
%
% \subsection{Modified \LaTeX\xspace commands}
%
% \DescribeMacro{\marginpar}
% The LaTex command |marginpar{abc}| with only one
% parameter it is modified to
% |\marginpar[left styled abc]{right styled abc}|
% maintaining page symmetry.
% If called with two parameters nothing is changed
%
% \subsection{Marginal note commands}
%
% All marginal note commands have five options followed by the side note text
% enclosed in braces. Each option has its own enclosing symbols. The option
% sequence is fixed but not used options are omitted entirely, including their
% enclosing sequence. The option sequence is \verb"*, ||, &lt;&gt;, (), !!" plus |{}|.
%
% ~
%
% % \begin{tabularx}{\textwidth}{ r X }
%   |*| &amp; margin note reference labels is omitted \\
%   \verb+|float offset|+ &amp; floating offset, negative is towards page top\\
%   |&lt;fixed offsett&gt;| &amp; fixed offset, negative is towards page top \\
%   |(custom mark)| &amp; any custom mark\\
%   |!colour!|&amp; any valid colour\\
%   |{content}|&amp; margin note content
% \end{tabularx}
%
% ~
%
%  \noindent Note: All marginals placed with a fixed offset, that is with the |&lt;fixed offset&gt;|
%  option can be overwritten by the marginals that float.
%
% ~
%
%
% \DescribeMacro{\sidenote}
% The |\sidenote| has five options
%  \verb+*|offset|&lt;offsett&gt;(custom mark)!colour!+
% all preceding the note |{content}|.
% The options are defined by their enclosures \verb+*||,&lt;&gt;,(),!!+
% and must be in the order listed above.
%
% Example: \verb"\sitenote|10pt|($\bigstar$){text}" is valid
%
% but \verb"\sitenote($\bigstar$)|10pt|{text}" will give an error
%
% ~
%
% \DescribeMacro{\sidenotetext}
% \DescribeMacro{\sidenotemark}
% \DescribeMacro{\sidenotetextbefore}  Similar to |\footnotemark|
% and |\footnotetext| the macros |\sidenotemark|, |\sidenotetext|
% and |\sidenotetextbefore| are provided, the latter two have the same
% options as |\sidenote|. This is useful in placing margin notes in
% environments where the |\sidenote| is not permitted.
% The margin note is not positioned by the |\sidenotemark|, but rather it
% is positioned relative to |\sidenotetext| or |\sidenotetextbefore|
%
%% ~
%
% \DescribeMacro{\sidealert}
% These are temporary margin notes rendered in red
% or by the user's defined |!colour!|. The package option |alerton| needs to be
% specified in the document preamble. The alert mark has zero width so it does not
% alter the main text layout and is also rendered in colour. The alert mark is
% either numeric arabic (default), or alphabetic if the side note mark is set to
% arabic
%
%
% ~
%
% \DescribeMacro{\sidepar} Starts a new paragraph in the side note,
% whereas |\\| begins a new line without indentation.
%
% ~
%
%\DescribeMacro{\sidecaption}
% The \verb"\sidecaption*&lt;offset&gt;[short form]{long form}"
% macro can be used from within figure or table environment and
% the caption is placed in the margin adjacent to the figure or table
% The float \verb+||+ is not an option here. Therefore, the caption might
% overlap with other marginals. Then, these marginals have to be adjusted with
% offset parameters. The formatting of the caption is done by the \emph{caption}
% package by defining a \emph{sidecaption} style. Please refer to the
% documentation of the caption package for information on styles. The macro can
% be starred, which is analog to the regular starred caption (no numbering, no
% tof entry). Use |\raggedinner| within the figure, or table, environment
% to place these near the caption.
%
% ~
%
% \DescribeMacro{\raggedinner}
% \DescribeMacro{\raggedouter} Are raggedleft or raggedright modes depending if
% document is one or two sided and if the page is even or odd.
%
% ~
%
% \DescribeEnv{marginfigure}
% The |marginfigure| environment puts a figure and its caption in the margin.
% Instead of |\begin{figure}[htbp]| use \verb"\begin{marginfigure}|offset|&lt;offset&gt;".
% Again, using an offset value switches the behaviour from float to fixed
% position. The marginfigure has its own caption style named \emph{marginfigure}.
%
% ~
%
% \DescribeEnv{margintable}
% The |margintable| environment works similar to marginfigure, but with table
% environments. Use \verb"\begin{marginfigure}|offset|&lt;offset&gt;" instead of
% |\begin{table}[htbp]|, its caption style is named \emph{margintable}.
%
% ~
%
% \DescribeMacro{\margincaption}
% The |\margincaption| macro is used only in the two above environments
% (|marginfigure| and |marginfigure|) and it is not to be confused with |\sidecaption|.
% It as the same options as |\caption|
%
% ~
%
% \DescribeEnv{figure*}
% The |figure*| environment is used to position figures across the full
% page, i.e. the text width plus the margin. The algorithm has to distinguish
% between recto and verso (left and right) pages and might need up to three
% \LaTeX{} runs to provide the desired result. The corresponding caption style
% is called \emph{widefigure}.
% \DescribeEnv{table*}
% The sister environment for tables is |table*|. Use \emph{widetable} to
% change its caption style.
%
%
% \DescribeEnv{text*}
% The |text*| environment is used to render text across up to
% the full page width. Page breaks are not permitted within this environment.
% This environment is useful when extra width for equations is required.
% The environment |\begin{text*}[0.5]| extends the text width by
% |0.5*(\marginparwidth+\marginparsep)|,  omitting the option is equivalent
% to specifying the option |[1]|,
%
%
% \DescribeMacro{\sidecite}
% \DescribeMacro{\sidecitebefore}
% % \DescribeMacro{\sidecitemark}
% \DescribeMacro{\sideciteafter}
% \DescribeMacro{\sidecitet}
% \DescribeMacro{\sidecitet*}
% The |\sidecite|, |\sidecitet| and |\sidecitet*| provide citing
% references in the margin and uses the package |biblatex| which has to be setup
% outside the |sitenotesplus| package.
% Use |sidecitebefore| or |sideciteafter| to place the marginalia reference
% before or after the |sidenotemark|
% Example settings  in the document preamble:
%
% ~~~~|\usepackage[english]{babel}|
%
% ~~~~|\usepackage[backend=biber,style=nature]{biblatex}|
%
% ~~~~|\addbibresource{mybibfile.bib}|
% \\The above three cite-commands use the same options as sidenote followed by the two
% options of the |biblatex|'s |\fullcite| command. Margin citations are always with marks,
% hence the |*| takes new meaning here.
% The command |\sidecite{BibReference}| and |\sidecite*{BibReference}| are
% equivalent, and both place a side note mark
% and the citation reference in the side margin. |\sidecitet{BibReference}|
% renders:  Author\textsuperscript{a}, where 'a' is side note mark, whereas |\sidecitet*{BibReference}|
% is the possessive version and renders:  Author's\textsuperscript{a}.
%
%
% \subsection{Packages loaded}
%
%   \begin{description}
%     \item[marginnote]
%        supports an alternative to \verb+\marginpar+ and creates non floating
%        notes in the margin.
%     \item[mparhack] to get \verb+\marginpar+ right
%     \item[caption]
%        allows to set figure and table captions in the margin and allows
%        easier formatting of these captions. Please refer to the
%        \emph{caption} manual for details on styles.
%     \item[xparse] is used to take advantage of the improved \LaTeX3 syntax.
%        All macros and environments are defined using this package.
%     \item[l3keys2e] provides a key/value mechanism
%     \item[xspace] provides the command |\xspace|
%     \item[changepage] is used to correctly shift figure* and table*. It has
%        to use the option [strict] to work properly. This might lead to an
%        option clash, if the same package is loaded without this option.
%     \item[ifoddpage] provides the command |\ifoddpage|
%     \item[etoolbox]  provides the command |\patchcmd|
%     \item[calc] provides calculation such as adding lengths
%     \item[ragged2e] if |Ragged| option is used, and provides hyphenation
%     to prevent very short lines
