Electron Energy Levels v1.2

v1.0: First release
v1.1: Inter-level navigation improved.
v1.2: Redid some of the get key commands so it's smoother within the
	levels.   *Addendum: I also redid the getkey commands on the
	homescreen.


Up: Next higher level
Down: Next lower level
Mode: Quit


Upcoming features:
Electron configurations of the 118 currently possible elements.
Possible porting to an app.

I tried using sprites to visually show the electron configurations, but
the program exceeded 10K by the 4th period, so I abandoned that
particular idea.  But, I'm working on a listing of all elements and
their configurations.
