Supplier Bill Parser

Parse bills scraped from a supplier website into bill and invoice documents. This module provides the general framework for setting up a supplier-specific parser in the docparse system. Each supplier-specific module will need to implement the actual parsing. This module subscribes the the changes feed and calls the supplier-specific parsing code when a new document is found


Each supplier parser is registered with seaport under the role parseScrapedFGS where FGS is the supplier code


When the parsing service starts up, it setups up a simple express server that reponds to post requests at the /parse/:scrapedID route. The service registers with seaport using the role role parseScrapedFGS. Seaport sends back a port and the parser server listens on this port


To parse a scraped document, issue a post http request to the /parse/:scrapedID route at the appropriate host and port, where :scrapedID is the _id of a scraped document in the database
