supported_cuba and contained_cuba methods for CUDS datasets

[nathanfranklin]

from @itziakos : https://publicwiki-01.fraunhofer.de/SimPhoNy-Project/index.php/Supported_CUBA_keys_for_container

• Each DataSet (ABCMesh, ABCParticles, ABCLattice) provides two new methods: supported_cuba(item_type) and contained_cuba(item_type)
  • each has the following arguments item_type : CUDSItem
  • returns the supported/contained cuba for that item_type

I think this is also related:
In abc_check_mesh.CheckMeshPointOperations, self.supported_cuba() should be supplied too. (i.e. create_points(restrict=self.supported_cuba())

reference: #202 , #203

@kitchoi , I totally agree. the testing frameworks (abc_check_mesh, abc_check_lattice..) should be updated to make use of the new supported_cuba(item_type) methods

Since the SSB is finalising the CUDS design, this should be put on hold until we define the CUDS more accurately, please remove from the current milestone.
