Usage

1. Check service is running by performing GET on /ping
2. Snap a website by making a GET request on /png with the following parameters:
   1. url - mandatory - url of the website, eg. /png?url=http://google.com
   2. fileName - optional - resulting file name, eg. /png?url=http://google.com&fileName=google.png
   3. selector - optional - snap only a part of the website described by a selector, eg. to get only the google logo by targeting element with id #hplogo: /png?url=http://google.com&selector=%23hplogo
   4. viewport - optional - provide optional parameters to alter snap service viewport, documentation here - eg. set width to 1280 and height to 1 (symbolic, will snap the whole page anyway) to : /png?viewport={"width":1280,"height":1}&url=http://google.com
