3013	OMEdit saves modified user's files at every run	massimo ceraolo	Adeel Asghar	"OMEdit saves modified files at every run.

If you've made a mistake on a model and you run that model, you find in extreme difficulty: no undo available, erroneous file on disk!
To avoid this, today, whenever you make modifications you've to manually backup your file(s). This is tricky and error-prone.

I think that OMEdit should not save user's files on disk by its own decision. If it needs a copy of the user's file(s) on disk to compile and execute, it should operate on temporary files it creates, without modifying user's.
