 ** Evil Mode
 Evil is an extensible 'vi' layer for Emacs. It emulates the main features of Vim, and provides facilities for writing custom extensions.  Evil Collection is also installed since it adds 'evil' bindings to parts of Emacs that the standard Evil package does not cover, such as: calenda, help-mode adn ibuffer.
