Added compatibility for vtk v.5
Minor cleanup.

'fake' fractional oxidation states are not allowed as bson dict keys)
bug fix with test_fit()
the test_fit function calls test_fit_with_mapper() with an additional parameter which will cause error when the test suite is called. Now, the "test" prefix is removed and the calling directly from unittest class is avoided.
