Description

The R client [[DataPackage]] class is currently a simple wrapper around a single data object. Need to extend it to support:

1) Multiple data objects
2) For each data object, one or more science metadata objects
3) for each data or science metadata object, a System Metadata object

Also need to add accessor methods to retrieve these objects, as well as accessors that extract and expose commonly needed information from the system and science metadata (such as dataset title, variable names, units, etc).

Partial suport for multiple data objects was added. Current packaging based on describes/describedBy rather than ORE packages, and so needs to be updated.

d1_client_r implements the new ORE resource map design, and can save all D1Objects and the ResourceMap that make up the DataPackage. Accessors for common fields within objects of the package need further design work, and probably need to reside in data format parsing classes (like EML, FGDC).
