% - find your API key (AKA Access token)at: 
%   https://www.pushbullet.com/account and set below.
% - use pushbullet('title', 'message') to send push notifications. 
% - Input must be string, so use sprintf to convert variables
%   beforehand. 
% - optional, can also provide api key if you'd rather leave it out of the
%   function (pushbullet('title','message','apikey'))
