An OCaml comment is `(* Some comment *)`. Like the C-family this can be
a multiline comment.
Recognize when the user is trying to commence a comment when they type `(*` and
then automatically insert `*)` on behalf of the user. A small convenience.

C has header and source files and you need to often switch between them.
Similarly OCaml has .ml (implementation) and .mli (interface files) and
one often needs to switch between them.
This commit provides a simple functionality that allows you to accomplish this.
