gridxy2

Plots colored gridlines. (A revision to gridxy needed for imagesc plots in MATLAB 7.10)

Example:
gridxy2(get(gca,'XTick'),get(gca,'YTick'), 'Color','y','Linestyle',':');
plots yellow X & Y gridlines at the same points as originally plotted on an imagesc plot.
The grid line locations can be arbitrary.
It can plot different colors for different axes, when called sequentially for each axis.
Original version hid the lines in MATLAB version 7.10.
