Example macOS text editor attempting to interact correctly with macOS text input systems. The goal is to have a good reference for implementing NSTextInputClient and NSTextCheckingClient. The goal is not to create a fully usable text editor.

Progress:

• NSTextInputClient - I think working mostly right, but probably not 100% right. Let me know what's wrong and I'll try to fix it.

• NSTextCheckingClient - Also mostly working, though I need to implement the interfaces in objective-c which is a little wierd.
