The example that is embeded in demo.py file has been used to create
the following 3 demos, and should now be available to use:
my_d() -- created from a file
my_cd() -- created from a file, a ClearDemo
str_d() -- same as above, but created via a StringIO object
Call by typing their name, (with parentheses), at the
ipython prompt, interact with the block, then call again
to run the next block.
