画线工具，功能需求：五个列表，前四列每一行都存放着不同的画线工具。第五列用于保存自己收藏的图形。其中每列都具有收藏和取消收藏的功能。
数据结构
第五列数组内容为空，在页面初始化时向服务器动态获取用户收藏的工具。

1 new list，写相关事件，点击事件可优化
分两步： 1.1如果list为第五个，写针对第五列的事件，用户取消收藏将服务器发送取消后的收藏结果，并且将取消元素移出当前组。
1.2 list为其他组，写不是特殊列事件，
用户取消保存改变当前收藏状态，将第五列元素对应的数组元素pop，将用户的收藏结果保存在服务器。
用户选择保存改变当前收藏状态，将第五列元素对应的数组元素push，将用户的收藏结果保存在服务器。
