Added a first stab at a CompositeStore. Also tested out that hte CouchdbStore put/add work as they need to (yay!). Added convenience method to StoreManager to get the store for a view and add it to the manager, retunring the same store thereafter. This is so that we can minimze the number of stores to the same view, so now all code really should take in a StoreManager if it was taking in a databse target url and view url.
