/**
 * Custom submit directive that will only submit when all the validation has passed
 * for all the fields. This extends on the ng-submit directive provided by AngularJS.
 * 
 * This directive will also remove the 'pristine' flag from all the fields when
 * hitting submit, allowing the form to display no errors until the submit button
 * is clicked/enter is pressed.
 * 
 * The variable 'app' is the instance of a module.
 * E.g. var app = angular.module('my-app', []);
