In Page and Cross Page linking mechanism

[LoveAndCoding]

There needs to be an easy way to link to a specific section. Linking to other page or inline content might look like this:

## Header Level 2
[Link Text][1]

 [1]: ##Header Level 2

If we use hash, it will likely need to be configurable, and something that has fallbacks, or warnings.

Crosspage needs to be handled. Punting on in page. That rabbit hole will need to be for later.

Links to the markdown file will be converted to links to the HTML file while rendering. Again, punting on the in page links for now.
