Initial checkin.  Examples don't work yet, but echonest package does.
Cowbell example works.  Starting in on reverse example.
Lots of hackery to get examples/reverse/reverse.py working.  Much refactoring left to do, but both cowbell and reverse examples are working now.
Updated audio.py comments.
New URLs for the API.
Added a basic readme file.
Added more installation notes.
Added AudioFile.audiodata attribute: presumed omission.
Conservative change: added AudioSegment, inheriting from AudioQuantum
Added fullSegmentsParser(), which uses all the data in get_segments, and
saves all data into AudioSegment.
More radical change: insert fullSegmentsParser() into AudioFile's 
list of parsers.
Introduced AudioQuantumList as our extension of list type:
 - has 'that' method, which allows for content-based AudioQuantum selection.
 - replaces output type in data- and attributeParser.
Undo change introduced in r15. Sometimes I'm an idiot.
Added selection.py with simple content-based selection functions.
Added examples/selection/, which demonstrates AudioQuantumList.that()
Deleted pesky .pyc from repository.
Deleted unnecessary audio.identity() helper function.
changed name of all() helper method to all_of()
copied in filters previously only in examples/selection/tonic.py
ExistingTrack class in audio that just takes a trackID
ExistingTrack can also take a filename, which means you assume the file has been analyzed already and the analyze API will just grab the data via MD5.
This commit got lost in the last one, sorry
fixed cowbell example
adding simple jingler example
