Two reasons to define another enum:
1. The old enum names are very long.
2. It includes FIELD_ASSOCIATION_POINTS_THEN_CELLS, which is not an
attribute type.

I had considered instead making a "ShortFieldAssociations" enum, that kept
things in the same order as the old enum but without the
"FIELD_ASSOCIATION_" prefix. This seems reasonable because they are no
longer just used for the FIELD_ASSOCIATION() key of the input arrays for
algorithms to process. It would still have a "point then cell" value that is
not an attribute type, but that is not too big a deal.
