# This class takes in a string of a markdown link and spits out
# a correctly formed markdown link, with absolute and relative
# links to markdown files correctly altered.
#
# The main thing we're working around is that markdown files can
# be linked to with (or without) an extension. That and we're also
# rewiring the filenames to be parameterized
