export big presentations to pdf
===== #####Requires node.js and npm (included with node now...)
==== #####Setup Replaced dependency on phantomjs and casperjs system installs by adding them as node modules, and using shelljs to call the local phantomjs...
npm install will set up phantomjs, casperjs, shelljs and pdfkit
===== #####Usage create pdf of pages 0 through 38 (all of 'em') of my playingwithfire presentation:
node bigout.js http://abenrob.com/playingwithfire/ 0 38
bigOut.pdf now sits in root!
===== #####Caveats/future work?
- phantomjs was doing weird things with pdf exports, so I did png only, and used pdfkit to make pdf
- needs better commenting
- needs better (any?) error handling
- needs tests
