[CM] pval in markov

[Rick Taube]

i think i have dynamic weights working with markov patterns now. its in  
rev. 1.6 of patterns.scm in CVS head. for instructions on installing by  
cvs see:

by the way, this sort of dynamic markov is pretty much what  i did to  
create a piece called amazing grace some years ago  if you want to hear  
with it sounds like here is a link to an  mp3 of the original  
performance (karlsruhe 1995 i think). the weights of 3rd order markov  
were slowly twiddled over time to cause the music to "congeal" into  
melodic and rhythmic tropes in the folksong
