add MapKit framework

https://developer.apple.com/library/ios/documentation/MapKit/Reference/MKLocalSearch/Reference/Reference.html#//apple_ref/occ/cl/MKLocalSearch
add gpx file for 48 Wall St
automatically sets "my location" to here
extract latitude from MKLocalSearch object
enable markers for user input
uses MKLocationSearch to translate 'Englishy' input to latitude longitude
adds marker to map at selected spot
so far only handles queries with a single result, I think
