Use `getproperty` to access fields ?

[rafaqz]

Hi, just startedf using Mongoc and it seems great, all working very easily.

But my first impression question is why doesnt getproperty work on Client, Database Document and other user-facing objects.

The syntax could look more like the mongodb docs, and would mean we would get autocompletion of the names for free in the REPL. Also probably dont want users directly accessing fields like handle.

It will require switching to using handle(document) rather than document.handle internally. Can PR if people are interested.
