Created a controller sub task generator.
This sub task was heavily inspired by generator-angular.

 The sub task will generate 2 template files: The controller and a unit test for it.

 To generate a new controller: 'yo gulp-angular:controller Thing'
 This will create Thing-ctrl.js under 'src/app/Thing/controlelrs'

 There are 3 options the come with it:
   --dest="path/to/whatever" : This will change the default path to what ever you entered under the 'src' library
   --coffee : Will generate coffeescript templates
   --component : Change the default path to sit under 'src/components'
