Doc - URI space

[coreation]

Currently there is no view on the URI space of TDT, so documentation on this should be made !!

[marc-portier]

effectively this becomes the documentation of the REST-API

suggestion:

• use a templating syntax to capture uri-patterns (http://code.google.com/p/uri-templates/)
• mention which methods are supported (and also support OPTIONS method to make the system self-documenting on that part)
• and also mention the response-codes (special attention for the error-conditions hinting at the normal client-resolution strategies) and the returned representations
