%DRAWBOX Draw a box defined by coordinate extents.
%
% drawBox(BOX)
% Draws a box defined by its extent: BOX = [XMIN XMAX YMIN YMAX].
%
% drawBox(..., NAME, VALUE)
% Specifies drawing parameters using parameter name and value. See plot
% function for syntax.
%
% drawBox(AX, ...)
% Specifies the handle of the axis to draw on.
%
% Example
% % define some points, compute their box, display everything
% points = [10 30; 20 50; 20 20; 30 10;40 30;50 20];
% box = pointSetBounds(points);
% figure; hold on;
% drawPoint(points, 's');
% drawBox(box);
% axis([0 60 0 60]);
