add internal utility for defining "type" property

[dwhieb]

Add an internal factory method utility for defining the type property on a model.

/**
 * A factory function that adds a `type` field to an Object
 * @param {Object} object The Object to add the `type` field to
 * @param {String} type The name of the type to add
 * @return {Object} Returns the original object
 */
function addType(object, type) {

 Object.defineProperty(object, `type`, {
 configurable: false,
 enumerable: true,
 get() { return type; },
 });

 return object;

}
