之前写了一些Cocoa控件的例子，现把代码放到git上。最近比较忙，有空再继续码
今天是2月22号，一个特别的日子。

1、三态button按钮

常态鼠标hover态鼠标press态

2、自绘link控件

3、一个简单的tableView

4、一个复杂的tableView

Menu
reveal menu item, to reveal app in the finder
reveal menu item only shows when only one row is selected
remove menu, can be used to remove one row at a time, or remove multiple selected rows at a time

Button
btnReval only shows at the row which the mouse hovers over
btnRemove only shows at the row that is clicked

Selection:
if only one row was selected, extends the heigh of row from 42 to 60
if multiple rows was selected, do not extend any row,shrink all the rows
