After discussion, we should tidy the APIs to provide the following:

server = RaphtoryServer(working_dir="/graphs",port=1736,config = ...)

server.start()

server.stop()

server.wait()

server.run()

c=server.get_client()

c=RaphtoryClient("localhost:1736")

c.send_graphs(hashmap_of_graphs,overwrite=True,namespace="ben")

c.load_from_path(path_to_folder_of_graphs,overwrite=True,namespace="shivam")

c.query(...)

Implemented this leaving the namespace argument which we will address once load is sorted
