Create VIM lockdown script where vimscript is not available => IdeaVIM (for PyCharm etc)

ideavimlockdown.py

"""
Script to create an .ideavimrc comptabile VIM lockdown key-remapper as used by github.com/hiway/po

This will unmap EVERYTHING and render your VIM useless - the idea is to begin with your own keymapping instead of VIM's legacy keymaps. You may refer to github.com/hiway/po for more information.

To create a new .lockdown_ideavim: `python ideavimlockdown.py > ~/.lockdown_ideavim` 
Then use it within your ~/.ideavimrc by adding "source ~/.lockdown_ideavim" within the file.
