Support for yield keyword and generator functions

[davidmarkclements]

Realize that these are ES6 features and this not in any browser (without being behind flags) at present, however

1) can be used with node --harmony 2) will be main stream before we know it 3) grasp would be great for converting some async code to yield based 4) grasp would be great for converting es6 generator code to es5 equivalent code with the same control flow

Great tool btw, loving the power.

Hi! Glad you like Grasp. Grasp will support ES6 once the library we use to parse JS, acorn, supports ES6.
