Intro to Rev stack up

[Judy Perry]

Hi,

For everyone who was interested, made suggestions and comments, and looked
over my project, a big thank you!

I have uploaded it to the User Space.  It is a very basic intro to the
Rev/HC model (stacks, cards, buttons, etc.) and a intro to mouse events.
It is ~6 MB.

Further suggestions, comments, flames (well, okay, no flames, please)
welcomed.  Thanks to Jacque & Andrew for their input and to everyone else
for their help with my questions!

Judy
