This is a great addition to our set of tools.  It would be nice to  
have  a choices dialog before writing so you can choose what channels,  
colors, merge method etc..  Does it use the color coding of the  
hyperstack to know how to merge?  What if you want to do a subtract  
before merge for gray/color merges?  Dave
