In order for the application to perform some 
datastore-specific functions, such as to execute 
a query that is not directly supported by JDO, 
applications might need access to the 
datastore connection used by the JDO implementation. 
This method returns a wrapped 
connection that can be cast to the appropriate 
datastore connection and used by the application. 
The capability to get the datastore connection is 
indicated by the optional feature string 
javax.jdo.option.GetDataStoreConnection.
