gmod_load_cvterms.pl does not (yet) support cross cv relationships

[bellerbrock]

Attempting to load related crop ontology terms in separate namespaces (e.g. "YamTrait" and "YamVariable") results in the error "Cross referencing relationships across namespaces is not supported (yet.. ) SKIPPING this relationship!".

So far, the way we get around this error is to load everything in a single namespace, but then we end up with mixed ontologies. Could we update the loading script to support cross referencing? The big advantage is that it would let us load more refined namespaces, which in turn would make it easy to distinguish which terms can have phenotype measurements linked to them, and how terms can be used for trait composing.

this issue will now belong in the Chado tools repository. I've recreated it there
