Added functionality:

HTDOC now has a few macros for sectioning. No default style file yet, as I'm
working on the bugs out to make sure numbering schemes can continue
indefinitely. At the moment, it is working with a particular style, and once
I'm sure it all works out, that will be added.

D object compilation is working. On the base trials, the dependency graphs are
properly calculating dependencies, and compiling only necessary things.
Only absolute imports are supported at the moment, however that will change
once the import statement class is updated.
