- This code originally written in June 2011 by Bill Caldwell (dynamicscrmdenver.com) from McGladrey
- This code was modified in October 2011 by Bill C to consume the latest yahoo geocode services
- This code was modified on 5/25/2012 by Bill C to provide international postal code functionality
- This code was modified on 6/27/2012 by Evan Kaiser to make the country field parameter optional, 
to allow the choice of using full or abbreviated state name, as well as to provide support for multiple 
browsers using the JQuery library.
- NOTE: Code requires that the page using it first includes a reference to JQuery and JSON. Here is a link to a
managed CRM solution containing JQuery and JSON2 Web Resources that you can include on your CRM forms:

o Parameters:
-- abbreviateState defaults to false, so unless it is specifically passed in as "true", it will use the full state name
-- The user is not required to enter the country (will default to US)
-- usage: ZipCodeLookup("address1_postalcode", "address1_city", "address1_stateorprovince", true/false, "address1_country");
