Metacat

removing unneeded class (never used)

cleaned up mock tests on hzObjectPathMap. split out code for mocking a datastore into MockObjectPathMap.

initialize Hazelcast from the custom configuration when initializing the Metacat service.

handle entryAdded and entryUpdated the same - update the entry if it exists, otherwise create it

handle entryAdded (to hzSystemMetadata) to store sysmeta to local store when it is not already present

make isScienceMetadata() method public/static to be called throughout Metacat

add code to handle new entry when it is not on the local member of the sysmeta cluster

clean up imports - randome quicktime package had been included

comment out processCluster connections that use hzClient until that is finalized

use HashMap, HashSet instead of the Tree* classes that require Identifier objects implement Comparable
