Detailed Description

Abstract base class providing plot and labeling functionality for a locus plot F:N->X,Y.

Locus argument N is assumed to be in range 0 .. MAX_N, and implicitly derived by enumerating all locus values. Override mpFXY::Rewind and mpFXY::GetNextXY to implement a locus. Optionally implement a constructor and pass a name (label) and a label alignment to the constructor mpFXY::mpFXY. If the layer name is empty, no label will be plotted.
