This code is intended to process and parse healthcare x12 837 (claims) and x12 835 (remittances) into human readable JSON format.
The claims/outpout can be forwarded to a NoSQL Data store like couchdb and mongodb
Usage :
    Commandline :
    # parse {x12}
    healthcare-io parse <x12_folder>

    # export {x12}
    healthcare-io export
