Metacat

Modifications to support the DataONE service API version 0.1.0. For DataONE, the get() and
create() services are partially complete. Several more functions and checks need to be added to
create() before it is viable. This DataONE support is not complete, and the current support breaks the MetacatRestClientTest for the time being (this client will eventually be removed).
