Scrape WHM DNS zone file editor and compare with another WHM zone

zone-scrape.js

/**
 * WHM DNS Zone Scraper
 * 
 * There are two steps to the process first login to WHM and start esiting the zone
 * file you want to sync from and run the first script beloew.
 * 
 * Take the output of that script and pass it as JSON to the oldEntries var on part 2.
 * Now run part two while editing the DNS zone to the target domain. This will
 * output the DNS entries that are not in the current zonefile in proper zone format
