[CM] Common Music 3

[Heinrich Taube]

a new "major version" of CM  is almost finished. The documentation on  
the new api is here:

	http://pinhead.music.uiuc.edu/~hkt/grace/doc/cm.html

most of the documented entries are already working in svn Grace,  the  
main things not yet done are the define-process macro and the Spectral  
Composition section. The former is a day's work the latter about a  
week. i would welcome any comments about the api or about things you  
think should be there (or not), especially wrt the new spectral  
compostion stuff.
