Detailed Description

Given a set of point identifiers, if a map is in effect (with its two axis endpoints) then both axis points must be handled as a unit.

For that to happen, for maps this class looks for one axis endpoint in a point identifier list, and if just one is in the list then the other is also added

This class has absolutely no effect (=noop) when a map is not in effect, or a map is in effect but zero or both axis endpoints are in the list
