[WIP] Initial version of creating a basic CMS

This is a complete tutorial on creating a simple (or basic) CMS from the PHPCR-ODM Standard Edition distribution using the RoutingAuto bundle.

See https://github.com/dantleech/tutorial-basic-cms

This was originally conceived as a blog post, maybe it should stay that way... not sure if we want to add tutorials for RoutingAuto when it is still not tested in the field, but then again maybe this is a good way to get it into the field :)

- [x] Add XML, YAML and PHP examples as required.
- [x] Break out an article on "Getting started with PHPCR-ODM" - remove the dantleech sf doctrine-phpcr-odm-edition
- [x] Misc code fixes.
- [x] Add root route instructions.
