* 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``)
* Added CSS based on Docco (blatantly copied).
* Updated sample text to better fit the emerging usage patterns. Some of the
things I did to make it render nicely for the Literate output may cause
problems when we go to render API output. I will cross that bridge when I come
to it.
* Added parsing infrastructure to the Generator behaviour to allow a
pre-processing pass over the document. Current the LiterateMarkdownGenerator
is using this to compile a map of `@org` references.
* Tweaked the HTML output slightly.
* Added a layer over the PegDownProcessor in LiterateMarkdownGenerator to
capture and transform `jlp://` links into relative links.
