基于CMultilineList类库实现MFC List (list control)的列表功能，并添加指定单元格可编辑功能

A custom control which provides a multi-column list with varying row heights, allowing multi-line text in the cells. Cell text is wrapped as necessary and may contain '\n' chars which will force line breaks. See LICENSE.TXT for licensing information wrt using this code in your project. To use, add MulilineList.h/.cpp to your project. The other files in this directory provide a demo project which shows the control in action and illustrates how to use it in your project.
