datamapper4rail 0.2.0

collection of datamapper related extensions. mostly needed to run within rails. the restful transactions is around filter for rails. the restful adapter can be outside of rails. datamapper store is a session store for rails which uses datamapper as persistent layer. the generators produces datamapper models for your rails application. quite a few things are "stolen" from dm-more/rails_datamapper. a lot of things do not work there and patches are still in process to be applied so until dm-more/rails_datamapper catches up, ut I hope these two project merge someday again.
