Review request for geode, anilkumar gingade, Barry Oglesby, nabarun nag, Dan Smith, and xiaojian zhou.


Repository: geode


Description
-------

Updated version to 6.0.0
Made modifications to use DoublePoint instead of LegacyDoubleField, IntPoint instead of LegacyIntField, etc
Added a temporary file to FileSystem.  This can be discussed as to how we want to handle this method.  Currently it creates a temporary, non distributed file.
SearcherManager creation now will pass in true for force deletes... This can also be discussed on what we want to pass in

Sorting the fileList due to new Lucene based test that requires the list returned to be sorted
