[Bprocessor-commit] gui/src/net/sourceforge/bprocessor/gui GUI.java,1.30,1.31

[Michael L. <he...@us...>]

Update of /cvsroot/bprocessor/gui/src/net/sourceforge/bprocessor/gui
In directory sc8-pr-cvs1.sourceforge.net:/tmp/cvs-serv31257/src/net/sourceforge/bprocessor/gui

Modified Files:
	GUI.java 
Log Message:
Implemented a simple Undo/Redo mechanism that remembers the entire model state for each operation Ð this may be too slow with larger models (and require large amounts of memory).

The history is cleared when saving the model.
