This namespace defines the handlers for general resources.

Simple handlers will only need to make a call to a library and then have that
data prepared for the client by standard response function. More complex
handlers will need to perform additional tasks. For example, in order of
increasing complexity:
* utilize non-default, non-trivial response functions
* operate on the obtained data with various transformations, including
  extracting form data, query strings, etc.
* take advantage of middleware functions that encapsulate complicated
  business logic
