Added example PDF form from website.

Blatently stolen from this URL:
http://www.thewebjockeys.com/TheWebJockeys/Fillable_PDF_Sample_from_TheWebJockeys_vC5.pdf

Unsure if this is MIT complient, only used for PDF form field
example.  Will replace with another PDF if needed.
Made small server that gives you a download of merged PDF's.
Added .gitignore for node_modules and generated files.
Added small shell script to merge PDF's using pdftk.

This bash script will merge together a PDF and FDF file, returning
an error to catch if something went wrong.
Added package.json for npm install's.
