added summary info to DistanceMatrixRequest and StaticMapRequest
added a LatLngComparer and tests to nail down problems with LatLng being deserialized in the json stream
made tolerance adjustment for LatLng testing.
added a JsonConverter for LatLng because it wasnt working before.  Maybe somebody looking around will see this and make the easy fix?
Attempted to rectify tests failing due to latlng conversion problems but ran into Elevation precision tolerance being ignored somehow.
Created a viewportcomparer to deal with viewport comparison
