Cross-ref between different markdown files.

[pykong]

I am using pandoc-include to break an otherwise big monolithic file into one root file including a set of smaller files.

This breaks however the autocompletion of cross-ref assets such as figures and listings.
(Citeproc citations still wotk throughout all files though, if PandocCiter.RootFile is set.)

I wished PandocCiter would account for such circumstance and still resolve cross-refs across file boundaries.

EDIT
To be clearer: All references (for tables, figures, listings, sections, etc. ...) as defined via cross-ref syntax in any markdown file should be resolved by PandocCiter in any other markdown file within the same project directory.

@notZaki thanks for this extremely helpful plugin!

I think I was able to implement this:

The only requirement is, that the file has to be open in one tab. But that's still a lot more convenient than no auto complete at all. I know and use a similar feature when writing SQL (opening the DB definition in one tab, having autocomplete for tables and columns for all other tabs!)

I have never written any typescript before, but if you think that's okay, I'm happy to send this as a PR @notZaki.

@pykong, just apply this patch and build it yourself for now if you still need it
