First python project : HP41 emulator + hints of workflow

[Liamtoh Resu]

New to the hp41c review and the pyhp41e emulator.

I was able to figure out the fast/slow switch, the roll down, xyzt rpn, rpn stack
and the trig/log/square/square root functions. ( I used the monkey typing on a
keyboard method without using any docs) I also figured out the virtual paper
tape printer.

Programming it will have to wait for now.

The emulator is a great rpn trainer for those who do not have any of the
classic hp calculators.

Thanks
