New files:  index and get-sakai

The index file serves as a table of contents of all files in this
directory, which is the root directory in this case.  Eventually, we
will have sub-directories and I recommend that we have an index file for
each of them.

I have also taken a crack at a "Get Sakai" file.  Currently, it links to
the installation instructions on Confluence for 2.9.  We should discuss
if release documentation will moved to the cle-documentation repo in the
future.

Technical Documentation Outline
Guidelines Document

I have created a set of guidelines that I hope will make it easier to
contribute to this documentation effort in a manner that provides some
structure and enables the later development of various deployment
strategies.

In particular, this document calls for three important elements:

1.  Documents shall be in strict XHTML.  This allows docs to be parsed
easily.
2.  An author DIV identifies the primary authors and subsequent
contributors.
3.  A version DIV identifies the first version of Sakai this applies to.

In addition to the above, I have made a statement about copyright that
assigns all rights to this material to the Apereo Foundation and
requires that all contributors sign an Apereo CLA first.
