The resources now properly process parts of the uri. This allows, for
example, certain sessions to be inspected. The current functionality is
only intended for testing and provides no useful functionality.
The actions taken by the resource manager are not done via the
inter-thread messaging system. When the implementation of the messages and
the JSON representation of the resources is done, the REST API resource
can actually be used.
The Resource class is intended to be an abstraction of a resource
tree. Each node in the tree can perform actions. The tree is traversed
depth first so that deeper command paths resolve to the correct nodes.
Currently all the base resources defined in the REST API documents are
implemented in a way that they return a 200 OK response to all
requests. When the internal data can be represented as JSON, the resources
can be hooked up to functions that generate JSON.
