Metacat

added exception testing to the crud test

getting getSystemMetadata to work

removed system.outs

removed CrudService dependency on servlet params. CrudService is now a singleton. I'm getting an error from metacat saying it can't find teh systemmetadata schema, even though it is, in fact, registered with metacat. need to identify why this is happening.

adding a system to track system metadata documents for dataone

Added initial implementation of getSystemMetadata and its associated REST service. Current implementation is returning a hardcoded system metadata document -- need to look up the real document for each guid and return that.

Completed main parts of CrudService.create(). Now the method writes both data and metadata objects along with their system metadata, and handles the mapping between global identifiers and local identifiers. Access control and logging still need to be dealt with to properly authenticate and then log activities.

Modify CrudService to write SystemMetadata to disk with an autogenerated localId and an autogenerated GUID. Validation depends on the DataONE schemas being setup in xml_catalog properly, so still need to check upgrade scripts to be sure these new schemas are added. Still need to handle the metadata document insert, but should be same as system metadata insert.

Refactored metacat to use dataone-service-api-0.3.0 jar file, with the new JIBX generated types and serialization. Included JIBX runtime jar in metacat to handle serialization and deserialization of SystemMetadata objects. Removed the old API jar file.

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).
