html.py

'''
All the functions in this file should produce pure HTML, as
opposed to Markdown or other similar languages.

Some folks want to work with systems that don't necessarily
support markdown (or deal with incompabilities between
different flavors of markdown), so when possible, we should
strive for pure HTML in our output in the future.

(Producing pure HTML doesn't have to be a burden--we can
add helpers/converters as necessary.)
