Resolving issue #169.

Hi @cjbj, I think we could cancel this pull request until we decide if we are going to keep DefinelyTyped or use typescript as a helper at JavaScript layer, so we can have this automagicaly generated (and so the api documentation).
What do you think?

Just to attach things - we discussed it, ending in lets wait at #333.
From that point to now (7 months), Typescript evolved a lot. I really think that it would be very nice to have the Javascript part rewritten in TypeScript generating the Javascript and adding definitions and documentation on it.

@Bigous thanks for the updated pull at DefinitelyTyped/DefinitelyTyped#10323 I think that is the right home for the definition file at the moment. You may recall I had some reservations about merging to node-oracledb and there are a bunch of other things (temporary lobs, longs etc) that need attention. If you close this, we can alweays reopen it later.

Sure, lets keep it separated for now and reopen later or create another one !!!
