early attempt at entity object
Entity class
add constructors for entity subclasses
move date functions to utils and add another test for entity subclasses
create one Synapse instance for multiple tests
fix id_of to raise exceptions
change names of unix epoch time functions
improved entity object
try an alternate implementation of Entity without changing the behavior of the dot notation
automate construction of entity_type_to_class map
removed entity2
fixed __repr__ method
improved entity.__repr__ and .__str__, added createDataEntity to integration test
made createEntity, updateEntity, getEntity and uploadFile work for Entity objects
patch up after rebase
revert to exceptions on 404, rather than return None
syn.updateEntity and syn.createEntity working but too complicated
first cut at synapse.get and synapse.store
