Concurent or Single process : data access to ONE-writer, MULTIPLE-readers Store with RAY

Here was another tricky thing I had to figure out. You can put this in the Docs too.

this was not obvious , you should add to the FAQ probably :

class Store(object):  .....

@ray.remote  #Ray Actor
class RemoteStore(Store): pass
