2.0.0-beta1

Major break from alpha1 (and the previous 1.x series) in that the generated
class names are significantly renamed.

In particular, the mapper class no longer has a "Mapper" suffix on it. This
helps it to act as a "base prefix" for IDE completion, which is now greatly
enhanced by the automatic addition of @method docblocks on the generated classes
to indicate type-specific returns.

If you have generated classes with the alpha1 release, you will need to re-
generate them and change your class references.
