Refactored the overall process, fixed #0005: link behaviour.

* Refactored the overall process flow. Instead of ``JLPMain`` handling the
  process, it now reads the command line options and defers to ``Processor`` to
  handle the actual process. The ``Processor`` instance is responsible for
  processing one batch of input files and holds all the state that is common to
  this process.
* ``JLPBaseGenerator`` and generators based on it are now only responsible for
  handling one file, generating output from a source AST. As a consequence
  state that is common to the overall process is no longer stored in the
  generator but is stored on the ``Processor`` instance, which is exposed to the
  generators.
* Generators can now be instantiated directly (instead of having just a public
  static method) and are no longer one-time use. Now the life of a generator is
  expected to be the same as the life of the ``Processor``.
* Fixed inter-doc link behaviour.
* Created some data classes to replace the ad-hoc maps used to store state in
  the generator (now in the ``Processor``)
