New docs: how to write \score

[Graham Percival]

There have been a few questions about how to write the \score section,  
or how to structure lilypond files, and whatnot.  I've written a few  
new documentation sections that should clarify this issue:

http://lilypond.org/doc/v2.7/Documentation/user/lilypond/Putting-it- 
all-together.html

Take a look at them; if they don't answer your questions on this issue,  
let me know.

Cheers,
