*  Added SharedFile file type for using large locally accessible files which doesn't copy a file as much as LocalFile.
*  Added many integration tests for MassStorageFile, SharedFile and LocalFile.
*  Added new exception types inheriting from GangaException to make reasons for the exceptions clearer.
*  Bugfix for GangaDataset and batch jobs #871
*  Improvements to the XML loading #839

ganga/python/GangaDirac
--------------------------------------------------------------------------------------------------------------
*  Added a universal check for all objects returned from calls to Dirac.
*  Added GangaDiracError exception type which is thrown when a command timesout/fails.

ganga/python/GangaLHCb
--------------------------------------------------------------------------------------------------------------
*  Cleaned up code for SplitByFiles, added more documentation.
*  Added new gridProxy object for backwards compatibility. This a wrapper around the new `credential_store`.
*  Default DiracProxy is constructed to be for `lhcb_user`.
*  Added function getAccessURLs to GPI to return a list of accessURLs for a provided list of DiracFiles or LFNs (strings).
Can access from the Dirac backend job.backend.getOutputDataAccessURLs(). #801
* Bugfix for GaudiExec. Now it checks that the SE is writable before attempting to upload the tarballs #852
* Update default LHCbDirac to v8r4p4

ganga/python/Ganga/GPIDev/Credentials
--------------------------------------------------------------------------------------------------------------
*  Integrated new credentials managment framework into Core.
*  Added AfsToken and VomsProxy for AFS and LCG credential managment.

--------------------------------------------------------------------------------------------------------------
ganga/python/GangaDirac/Lib/Credentials
--------------------------------------------------------------------------------------------------------------
*  Added DiracProxy to allow for managing multiple proxies.
*  New grid proxies can be constructed via `credential_store.create(DiracProxy())`.
*  New grid proxies can be destoryed via `credential_store.destroy(DiracProxy())`.

*  Default DIRAC proxy group is now managed via `[defaults_DiracProxy] group = myvo_user` in your .gangarc.
