OWL Role Grouping Change

This feature brings better role grouping from OWL axioms into the inferred form.

In OWL axioms any self grouped attributes are explicitly grouped in the OWL expression and will be transformed into a group other than zero by this toolkit for use in an authoring UI. This release lets this explicit grouping flow through into the inferred relationships also. So any relationship which was previously in group 0 in a stated relationship and declared as groupable in the MRCM will now be moved to its own positive group number. This will happen during classification once the edition has been converted to use axioms for it's stated form.
When stated relationships are used for classification there will be no change in behaviour.
