- more work done on file systems and stores:
 * initial cleanup of storeBase2 (future base class for stores)
 * some implementation and experimentation for nodeFS and nodejsStore
 * started adding tests (was about time !)
 * note : the nodeFS/ nodejsStore is going to be an issue with
the current way the tests are run (in the browser)...
 * still nothing functional, toying around with the best way to have all necessary features in stores and fs
BUT keeping them independant from any backbone-marionette specific elements such as vent etc , as they will be moved
to the new kernel and should be relatively low level ...
