Metacat

insert/update documents with null user and null group to circumvent access control restrictions then update the user_owner and user_updated values to reflect what exists on the originating server (pisco)

use 'user_updated' field when writing the replicated document - allows most recent ownership/permissions to be used (in case LDAP groups have shifted) and is more accurate for both updates and initial inserts (hopefully addresses the replication issue we are having with pisco)

add support for temporal element query in pathquery

DocumentImpl.delete() now throws finer grained exceptions (not a general exception). Consequently, the classes that call it have been updated to handle the thrown exceptions, including CrudService, ReplicationHandler, and ReplicationService.

refactor the names of these Data Manager implementation classes so that it's easier to use them with the default/local versions of similar. These classes utilize Metacat-specific configuration values rather than relying soley on the bundles that are used in the stand-alone DM lib.

To support GUIDs in MetacatHandler.handleDeleteAction(), I've added in a new method:
deleteFromMetacat() - deletes a document based on the docid
This factors the deletion code out of handleDeleteAction(). handleDeleteAction() now does a docid lookup based on GUID, and if it is not found, reverts to the deletion based on docid instead.

These are fairly significant changes to MetacatHandler.handleInsertOrUpdateAction() that add in support for creation or update of GUIDs and SystemMetadata. Upon insertion or update of DataPackages from non-DataONE aware clients (such as Morpho), the identifier table is updated by creating a GUID, and the systemmetadata table is updated with fields after the EML document is parsed for distribution information and entity typing. System Metadata documents are also generated and inserted into Metacat. The list of data entities is iterated over and System Metadata is generated for each data file as well.

In MetacatHandler I've removed updateSystemMetadata() in favor of additions to insertOrUpdateSystemMetadata(). Modified createSystemMetadata() to reflect the changes as well.

Modified MetacatHandler.createSystemMetadata() to take a localId, not a guid as an argument since there are times when the guid has yet to have been created, and it is created in this method if so.
Also, put the read() call to get the InputStream of the data/metadata document into it's own try/catch statement.

Somehow missed adding in javadoc for read(). Here it is.
