Created PHPCR-Shell documentation

[dantleech]

Started documenting PHPCR-Shell.

This PR contains:

• Installation
• Connecting
• ...

[dbu]

maybe we should say: "DoctrinePHPCRBundle version 1.2 or newer"

[dbu]

well done. do you plan to add some usage examples, or a full usage reference? maybe having just a tutorial and explain how to let the show document itself is actually more efficient than a reference that needs to stay in sync with with the tool...

[dantleech]

I think yeah, just some usage examples, how to query, how to navigate, etc. As for a reference, we could generate that from the commands themselves - which might be a good idea as it would help expose any inaccuracies there.

[dbu]

either generate, or just explain to the user how to use help to get self-documentation. then he always has the documentation for his currently installed version.

[dantleech]

Have updated with a generated reference.

Will merge this tomorrow.

[dbu]

please have the generator generate a .. comment to tell this is generated and where to edit if something should be improved. avoid PR on this file :-)

Done
