/* 

getAddLatLng(address)

This is an async function that retrieves the longitude and latitude, given an address as a string.
Since we can't return a value in the call back function, because it might still be processing,
instead we set the new point using setNewPoint, and then later retrieve it using getNewPoint
(after the call back function completes)

This function is to be only used when inserting new listings, as Google's getLatLng uses alot of resources, and takes time to process.
