list2img returns a cell array, this needs work before being called by Ncolor.  This is now it's own function.
Also some minor bug fixes to companion codes.
Fixed bug in frame as color -- wasn't actually using frame info, just order of dots in the mlist.  Now fixed.
Ignoring Demo Data for now.
Updated color controls for STORMrender
New function ColorByFrame integrated to STORMrender
