21 ---Purpose: This class implements the algorithms used to
22 -- create the bisecting line between two 2d points
23 -- Describes functions for building a bisecting line between two 2D points.
24 -- The bisecting line between two points is the bisector of
25 -- the segment which joins the two points, if these are not coincident.
26 -- The algorithm does not find a solution if the two points are coincident.
27 -- A Pnt2dBisec object provides a framework for:
28 -- - defining the construction of the bisecting line,
29 -- - implementing the construction algorithm, and consulting the result.
