Introducing docs/ directory

The need for documentation has increased as the project matures and gained popularity. To this end a "User Guide" and a "Developers Guide" has taken shape. The initial code dump (original patch was ~4MB, hence not posting to list first!): https://git.fedorahosted.org/cgit/scap-security-guide.git/tree/docs This initial patch should provide a base framework to build out these documents, and should be considered alpha/draft. The intent is to provide a User Guide which comprehensively documents the usage of SSG, and a Developers Guide that details out our build process, coding standards, and other information a new project member would find useful. This code is currently running at http://docs.ssgproject.org/, however I can't stress enough the need to consider this alpha/beta at best! At some point Jenkins may be setup to push doc updates to docs.ssgproject.org .... help would be much appreciated if anyone knows Jenkins!
