Restructure to export specific modules

[watzon]

This is a great library first off. My only qualm is that in order to import it I have to use the outdated /// <reference_path ... />. Ideally this library should be findable by the typescript compiler by having an index.d.ts file in the root directory. Modules should also ideally be importable by using import { Module } from 'tsmonad. If you'd like I can submit a PR

Thanks, that is a really good idea. A PR would be welcome as I am currently not able to spend much time on this project.

Sorry, I have no time to look into this. Please reopen if it's a concern.
