Extra utilities for use with portable-hack-ast.

Why this repo?

Why is this not part of portable-hack-ast?

Portable Hack AST should rarely need new feature updates. Chances are small, but not zero, that the AST has a breaking change. This would mean that portable-hack-ast would have two incompatible versions.

Since upgrading to hhvm 6.33+ requires a lot of effort, I don't want features to become exclusive to the latest version. By giving accessories like this a home in this repository, I assure myself I have a place to add "extras" which can be used regardless your hhvm version.
