/* NOTES
 * With CREA, You have to ask the RETS server for a list of IDs.
 * Once you have these IDs, you can query for 100 listings at a time
 * Example Procedure:
 * 1. Get IDs (500 Returned)
 * 2. Get Listing Data (1-100)
 * 3. Get Listing Data (101-200)
 * 4. (etc)
 * 5. (etc)
 * 6. Get Listing Data (401-500)
 *
 * Each time you get Listing Data, you want to save this data and then download it's images...
