Add location to AST

[cmkilger]

I'd like to get the location of each node of the tree relative to the original input text, either line/column or number of characters from the beginning. I was looking for a way to add it, but I don't quite understand the code that well yet, and it didn't seem straight forward to implement.

And I do see start and end lines for blocks, but I want it for each inline as well, e.g. text, emphasis, html, etc. I also saw that the start line wasn't set for some headers. Bug?

Unfortunately source positions for inline elements aren't always useful: commonmark/commonmark.js#64 (comment)

I'd like to monitor how the upstream projects handles this (possibly using source maps instead) and the implement the same approach for consistency. I'm therefore going to close this issue (for now, at least).

Quite possibly. If you wouldn't mind opening a separate issue (with some examples of this bug) I'd greatly appreciate it!

Thanks!
