Save Experiment SnapShot with Date+Time Stamp Suffix

I often need to save snap shots of experiments with brief notes in case I need to return. This saves a snap shot of the current experiment with a date+time stamp suffix. It puts a global string SnapShotNote with comments before saving. Saves to home directory (same as current experiment) or to user's choice if first time. Recognizes if the current experiment is itself a snap shot. Relies on a function to create the date + time stamp.
