local Node/Browser development with Chrome DevTools

Runs a source file in a Chrome DevTools process. Saving the file will reload the tab. This is useful for locally unit testing browser code with the full range of Web APIs (WebGL, WebAudio, etc). It provides access to profiling, debugger statements, network requests, and so forth. It can also be used to develop typical Node projects, or as a generic Node REPL. For example, instead of using nodemon during development, you can use hihat to make use of a debugger. Since it provides Browser and Node APIs, it can also be used for some simple CLI tooling, like saving a Canvas2D to a PNG file. Eventually; this may be useful for headless testing of Node/Browser code on a server. Under the hood, this uses electron, browserify and watchify. Currently only tested on OSX Yosemite.
