//=================
// AddressGo flow
//=================
/*
	Summary:
		AddressGo attempts to parse input into a matching property by ML# or address.  
		If neither of those match it forwards the user to the appropriate PropertySearch page.
		Central to the process flow is the SearchOptions structure which is populated within 
		the SetSearchOptions function to be appropriate for the site code.

	Steps:
		1. Set SearchOptions to be appropriate for the site. (MFR, SND, etc.)
		2. If the input is blank determine whether to exit based upon the site.
				*SearchOptions.ExitOnEmptySearch : boolean
		3. If the input matches MLNumber syntax Call MyAjaxService.PropertyMLLookup wait for the callback and we're done. 
				*SearchOptions.MLPattern : regex
		4. Parse input into address and zip
		5. Call MyAjaxService.PropertyAddressLookup.
		6. Receive the callback from PropertyAddressLookup.
		7. If PropertyAddressLookupCallback receives a valid SysPropertyId then go to PropDetail for the property and we're done.
		8. Strip the last word from the address lookup and recursively call PropertyAddressLookup 
		9. Repeat previous step until we find a result or there are 2 or fewer words. 
		10. If no match can be found we forward to the GotoURL location
