A core for a text editor, may support advanced function and latex rendering in the future.
Now focus on basic functions, initially finished, but may still have bugs and need more tests.
Support undo redo and some basic functions such as insert and remove
In theory, it can be embedded in any ui of text-editor with any rendering engine or platform, also a good source for study.
It is still on developing but just passed the first round of test.
