markdown headers rendering as a table at the top of all files

[stephhazlitt]

Many/most of the .md files have a header section that renders as a large table in html.

If the behaviour is intentional, then this issue should be closed. If not, then I think the metadata can be captured in a way where the information does not render at the top of each html page—which makes the reader have to scroll quite a ways to get to the page content.
