Opal corelib

This is the Opal corelib implementation API documentation. The whole corelib is loaded upon require 'opal'.

The runtime.js documentation is available here (in master)

Cherry-picking

Note that require 'opal' will load all of the corelib, which is likely to have a ton of stuff you don't need.

If you're concerned about runtime size, you can require 'opal/base' and require anything you need, or require 'opal/mini' to have a working Ruby without useless stuff.
