es6

[jonathonfletcher]

src/main.js is now a 'clean' es6 import.

• jshint -> eslint
• browserify -> webpack (via babel)
• custom footer for module.exports

The es6 import is the main work. This means that:

import solver from "./src/main.js"

is now valid. We can now use this form to import directly from TypeScript.

grunt is still the build system, but browserify / jshint / uglify are now replaced by webpack / eslint / babel.
