Added properties for apomorphy-based phyloreferences.

These are has_Progenitor for typing the ancestral node where the apomorphy first appeared, and BFO:part_of and BFO:has_part for the phenotype class expression.
Added apomorphy phenotype using has_Progenitor.

This is according to "the first sarcopterygian to have possessed digits homologous with those in Homo sapiens, and all its descendants" (Anderson 2002).
Adding example for querying an apomorphy-based phyloreference.
