Highlight code blocks

[rafaqz]

Julia makes it really easy to run string macro code blocks for at least R and Matlab. But in vim they are highlighted in all green! It's an impediment to using other languages freely.

Vim markdown has code block highlighting (with g:markdown_fenced_languages etc), could something like that be possible for julia? It may be as easy as copying the markdown highlighting code and changing the regex to match R"""/""" and mat"""/""" and similar.

Seems like it could be a good idea. Care to submit a pull request?

Ok, see what I can do. It might be a week or two until I get around to it.
