[Rivet] plotting of multi-weight curves in 3.0.0alpha1

[Andy Buckley]

Hi Christian,

I'll look into improving this. There might be a few things that need to 
be upgraded to understand those new extended paths, as well as making 
rivet-cmphistos itself a bit more flexible -- I just hacked in something 
that would demonstrate the multiweight ability; should have known that 
enhancements would immediately be requested ;-)
