- Moved the Language model and struct pruning tutorials from the Wiki to
the HTML documentation.  Love the ease of Wiki, but GitHub doesn't let
Google crawl these pages, and users can't open PRs on Wiki pages.

- Updated the pruning algorithms documentation

Latest versions of Jupyter notebooks have a different syntax for
launching the server such that it listens on oll network interfaces
(this is useful if you are running the Jupyter server on one machine,
and connect to it from a browser on a different machine).

So:
	jupyter-notebook --ip=* --no-browser

is replaced by:
	jupyter-notebook --ip=0.0.0.0 --no-browser

* Implemented as a Policy
* Integrated in image classification sample
* Updated docs and README

* Scale of bias and parentheses were wrong
