Because every serious text editor needs a nyancat plugin to prove its worth.
Inspired by: Emacs Nyan Cat mode (https://github.com/TeMPOraL/nyan-mode)
Install plugin. Use. Have a look!
This hasn't been thoroughly tested, beacuse thoroughly testing is not in the spirit of nyancat.
(Also this is my first Atom package so if I break everything in your editor, plz just uninstall nyancat.)
