To add Minc functions to the Cmix kernel just
define them as type double, make sure they return
something, introduce them in ug_intro.c and then
add them to the Makefile.  From then on all applications
you build will have these Minc functions.  Check out
m_misc.c or m_pitch.c in this dir for examples of
these kinds of functions.  The complete list of
'generic' Minc functions is thus contained in 
ug_intro.c

Currently:  (The names in quotes are how Minc sees them, 
		and the right-hand version is how the compiler
		sees them.  The m_ tradition is to avoid 
		compiler confusions)
