The ZadronsPouch example was moved to bjc-utils, because it didn't use
any RGens specific code

This moves some documentation to a specific docs folder, as well as
creating a new examples folder, and putting the two pieces of example
code into there

It is now in StandaloneMarkov, which is the produced type anyways. This
also allows the removal of the StandaloneTextGenerator file, as it no
longer contains anything
