前几天空闲的时候，实现了一个2048游戏。除了可以设置行数和列数之外，支持修改显示名称，比如下面，改成神雕侠侣中的角色名称：
游戏逻辑比较简单，大家都应该玩过。
这里主要实现了四个类：game、gameboard还有colorblock和boardgridline。
game类主要用来实现游戏的控制，比如初始化、添加新的色块、移除色块、控制色块上下左右移动、改变积分，触发游戏结束等。
gameboard继承自canvas，实现了色块的合并、检测每个格子的状态等，另外提供了game控制色块移动的接口。
colorblock类继承自shape类，用于自定义色块的显示，包含xy坐标、颜色、显示文字等依赖属性，可以进行动画，另外还实现了具体的上下左右移动的方法。最初几个颜色是手动设置，等到色块越来越多，就随机生成一种颜色。
boardgridline也继承自shape类，用于绘制canvas底部的网格。
另外，游戏使用一个简单的文本文件保存设置，包括行数与列数，以及显示文字及其对应颜色，具体操作在settings类中。
最后，按键事件封装在keysnavigation中。
图标使用expression design制作：
游戏效果如下：
