COMMONS12 — Several properties in the quantities and units ontology are overly constrained

One example of this is hasNumericValue. It is currently declared to be functional, but could be the parent property for several properties of some class. In this case, the resulting ontology could be logically inconsistent if the values are not the same (and even if they are, by coincidence, that's still a problem). Other properties that are also declared as functional should be reviewed for the same issue.
