Rule group tests

Adds code coverage in for the component

Also I would prefer to keep the tests next to the source files. Right now we have it in a separate test folder. Would you be ok moving them inside lib and rename them to *.test.js ?

With that the file glob in karma gets simplified as well

Fixed this by also adding babel-preset-es2015. There is still a failing test:

<Rule />
    onValueChanged
      ✖ should call the onPropChange with the rule id
        PhantomJS 2.1.1 (Mac OS X 0.0.0)
      expected 'value' to equal 'any_field'

sure i can move them back to with the source files. I've seen it done both ways (i've just come from a background where they are separate).

I'll take a look at that test failure. I typically try to do rm -rf node_modules then npm install then npm test to see if my changes are working but maybe that's not catching everything
