neume

Copperbox revision 2629.

I've started a new revision of Neume - I was going to wait until I had more time at the Christmas holidays to do this but I got itchy feet...

Instead of building a syntax tree, transforming it and printing it; I'm going to see if I can use only monadic building (no transformation). This means that you have to be very cognisant of what you are building (you can easily build junk) but it may be less brittle than previous versions which struggled to cope with LilyPond's wild syntax. LilyPond's syntax is not at fault - music notation has had a thousand years to develop a truly unwieldy grammar.
