ii) Creates image objects and links them to users.
iii) Annotates all Images(All users/groups :  Exhaustively).
iv) TESTS moves between all groups (Exhaustively).

To test, (via commandline)
export ICE_CONFIG=<PATH TO ICE CONFIG>
ex:
export ICE_CONFIG=/Users/bramalingam/OME/openmicroscopy/dist/etc/ice.config

then, (cd into the local git repository --> openmicroscopy)
./build.py -f components/tools/OmeroJava/build.xml test -DTEST=integration/PermissionsTestAll

--The test should take around 9 minutes.
--The result should look something like this :
