Added some small bug fixes.
Major new features/classes:
MetaCorpusDB: a class for storing a corpus consisting of soundfiles, DERIVATIVE SOUND FILES, and all associated metadata
CorpusSoundFileTree: a "helper" class for structuring the above.
Also, there are some new GUI classes with "Meta" versions. These will be merged with the non-Meta versions at some future revision... These classes are somewhat new and therefore rather raw. Have a look and ask questions.
You can get it at https://github.com/kitefishlabs/cbpsc/zipball/0.5. It should work with the latest Mac version of SuperCollider (3.4.4). Non-GUI classes are cross-platform, but GUI classes are Mac-only.
