/**
 * Provides a service client for accessing the Microsoft Azure Table service.

*     http://myaccount.table.core.windows.net
* For more information, see the MSDN topic Addressing Table Service Resources. *

* The credentials can be a combination of the storage account name and a key, or a shared access signature.
