Emacs-like hotkey support for wxPython

Some people have a burning need for Emacs-like multiple key sequence Hotkeys. What do I mean? Ctrl+x Ctrl+S to save the currently open document and Exit emacs. Included as code is a sample wxPython program which implements multi-group keypress combinations, and will print `hello!` in the statusbar if the Combination Ctrl+Y Alt+3 Shift+B is entered. As you are entering a valid sequence of hotkeys, it will print your current combination in the status bar. If you make a mistake, it will print out your failed keyboard combination.
