clear和backbone中的unset有什么区别？ （两人return一件事）
-unset 从模型中删除属性。
unsetmodel.unset(attribute, [options])
Remove an attribute by
deleting it from the internal attributes hash. Fires a "change" event
unless silent is passed as an option.
-clear 从模型中删除所有属性。
clearmodel.clear([options])
Removes all attributes from the model,
including the id attribute. Fires a "change" event unless silent is
passed as an option.
