#@TODO: This is a flag that may be set externally by previous commands.
#Example: In BuildDna_EditCommand (graphicsMode), if you want to join
#two strands, upon 'singletLeftDown' of *that command's* graphicsMode,
#it enters JoinStrands_Command (i.e. this command and GM), also calling
#leftDown method of *this* graphicsmode. Now, when user releases the
#left mouse button, it calls leftUp method of this graphics mode, which
#in turn exits this command if this flag is set to True
#(to go back to the previous command user was in) . This is a bit
#confusing but there is no easy way to implement the functionality
#we need in the BuildDna command (ability to Join the strands) .
#A lot of code that does bondpoint dragging is available in
#BuildAtoms_GraphicsMode, but it isn't in BuildDna_GraphicsMode
#(as it is a SelectChunks_GraphicsMode superclass for lots of reasons)
#So, for some significant amount of time, we may continue to use
