This is a pathetic attempt to make samples for the library.
It suffers the same problem as the library itself: no time.

It should get better soon

In order to fully understand this (and use the hundreds of things not
demonstrated), you should:

a) Read the XForms docs
b) Read the pyxforms/__init__.py file
c) Read all the .c files

Anyway, it's just a sampler, this should get MUCH more complete soon
