Hi S,
	There is support for multiple Amber trajectory files, but not DCDs.   
So I took the multi-file Amber code and with some pushing and pulling  
added it to the DCD file code.  So in tomorrow's build you will be  
able specify multiple DCD files initially, or add additional DCD files  
with the Movie interface's File...Add Additional Frames menu entry.
