$id, vm的名字
$watch, 用于添加监听函数
$fire, 用于触发监听函数
$events, 用于储存监听函数
$model, 返回一个纯净的JS对象
$element, 2.0新增, 当我们用ms-controller,ms-important指定一个VM的作用域,对应元素节点会放到这个属性上.
$computed, 2.2.1新增,用来集中定义计算属性

pushArray(el), 要求传入一数组,然后将它里面的元素全部添加到当前数组的末端。
remove(el), 要求传入一元素,通过全等于比较进行移除。
removeAt(index), 要求传入一数字,会移除对应位置的元素。
removeAll(arrayOrFunction), 有三种用法,如果是一个函数,则过滤比较后得到真值的元素,
如果是一数组,则将此数组中与原数组相等于的元素全部移除;如果没有任何参数,则全部清空。
clear(),相当于removeAll()的第三种方法,清空数组的所有元素。由于需要同步视图的缘故,不能通过vm.array.length
= 0的方法来清空元素。
ensure(el),只有当数组不存在此元素时,才添加此元素。
set(index, el),用于更新某一索引位置中的元素,因为简单数组元素的数组,是不会转换它的元素
toJSON(), 用于取得数组的$model, 2.2.2新添加的方法
