// Note for use on any Form with Address Input.
// add HN.setUpAddressSuggestions to OnLoad Event, and add the schema name of line 1 address field. 
// ie shipto_line1, or address1_line1 default is address1_line1
//
// add HN.onSaveAddress to OnSave Events, and add the sche scheed name of the line 1 address field. 
// ie shipto, or address1 default is address1
