Construct a Point2Endpoint with nAxes specified; nAxes must equal template parameter N.
This constructor is primarily used by Transform; other users are encouraged to use the default constructor.

overridevirtual |
Check that framePtr points to a Frame, not a subclass.
Subclasses are forbidden because lsst::geom::Point2D is assumed to be cartesian and subclasses of Frame are not (e.g. SkyFrame, SpecFrame and TimeFrame). Note that SpecFrame and TimeFrame are 1-dimensional so they cannot be used in any case. A CmpFrame could be cartesian, but we play it safe and reject these (however, a cartesian CmpFrame ought to simplify to a Frame).
Reimplemented from lsst::afw::geom::BaseEndpoint< PointT, ArrayT >.
