Cannot use predefined facility arrays other than the default.

[baagaard-usgs]

A facility array other than the default cannot be bound to a Pyre FacilityArray. The facility array object is treated as an array with a single component rather than a facility array object, like the default.

This is associated with the implementation of the FacilityArray object in Pyre. See geodynamics/pythia#1 for more inofrmation.

Workaround is to create a derived class for the object holding the facility array and change the default factory for the facility array.
