function h = gcp
%GCP    Get current point on current axes and current figure.
%       H = GCP returns two sets of points:
%             1) the current point on the current figure;
%             2) the current 2-D point on the current axes. 
%
%       The current point is the last place on an axes that a mouse
%       button was pressed (or released if dragged).
%
%       The first set (figure point) is not useful for most purposes.
%       The second set (axes point) can be used to get the axes location
%       at which to place text strings for labelling.  
%
%       The current points are returned in a 2X2 matrix, with the units
%       specified by the figure (axes) property 'Units', as:
%
%         |                  |
%         |  Fig_X     Fig_Y |
%         |                  |
%         | Axes_X    Axes_Y |
%         |                  |
%
%       The figure units are most likely to be in pixels.
%
%       See the MATLAB Reference Guide for details on the 'CurrentPoint'
%       property of figures and axes.
