Final release of version 0.2.0

* Changed syntax such that new classes are returned on creation and can
be stored in any variable.

* Classes no longer toString to a nice name of themselves. Rather they
toString to what a JavaScript developer would expect.

* Speed has been improved by about 30% for both initialization and
method calls

* Total code size has been reduced by about 20%

* Code can now be compressed with uglify without the compressed code
needing changes to work.
