ticklabelformat - set a dynamic format of axes tick labels

ticklabelformat sets the format of an axes tick labels based on sprintf format specifiers. The format is preserved during zoom/pan/maximize and applied to the dynamic tick values.

Calling ticklabelformat with an empty ([] or '') format will revert to Matlab's normal tick labels display behavior.

Syntax:
ticklabelformat(hAxes, axName, format)

Input Parameters:
hAxes - handle to the modified axes, such as returned by the gca function
axName - name(s) of axles to modify: 'x','y','z' or combination (e.g. 'xy')
format - format of the tick labels in sprintf format (e.g. '%.1f V') or a
function handle that will be called whenever labels need to be updated

Examples:
ticklabelformat(gca,'y','%.6g V') - sets y axis in current axes to display 6 significant digits
ticklabelformat(gca,'xy','%.2f') - sets x & y axes in current axes to display 2 decimal digits
ticklabelformat(gca,'z',@myFcn) - sets a function to update the Z tick labels in current axes
ticklabelformat(gca,'z',{@myFcn,extraData}) - sets an update function as above, with extra data

Warning:
This code heavily relies on undocumented and unsupported Matlab functionality. It works on Matlab 7+, but use at your own risk!
