%% BOX_CONTAINS_POINT_2D determines if a point is inside a box in 2D.
%
%  Discussion:
%
%    A box in 2D is a rectangle with sides aligned on coordinate
%    axes.  It can be described by its low and high corners,
%    as the set of points P satisfying:
%
%      BOX(1:2,1) <= P(1:2) <= BOX(1:2,2).
