imagemenu

Adds a context menu to change image properties.

IMAGEMENU adds a context menu to change image properties
IMAGEMENU(handle) creates a context menu for all images with the parent
handle that allows image properties to be easily changed.
IMAGEMENU, without any input arguments, will create this context menu
for all images that are found in the current figure.
This allows users to easily change image properties, and is especially
useful for compiled programs, as users do not have access to MATLAB's
property editor.
