Rename the module provider function names

[levilindsey]

I think that modules should look like the following.

In the current implementation, the provider function is instead called appXxxx.

(function () {
  angular.module('appXxxxDirective', [])

    .directive('appXxxx', provider);

  function provider() {
    return {
      restrict: 'E',
      scope: {
      },
      templateUrl: 'components/...',
      link: link
    };

    // ---  --- //

    function link(scope, element, attrs) {
    }
  }
})();
