Constructs a LatLngBounds from doubles representing a LatLng pair.

This values of latNorth and latSouth should be in the range of [-90, 90], see GeometryConstants.MIN_LATITUDE and GeometryConstants.MAX_LATITUDE, otherwise IllegalArgumentException will be thrown. latNorth should be greater or equal latSouth, otherwise IllegalArgumentException will be thrown.

This method doesn't recalculate most east or most west boundaries. Note that lonEast and lonWest will be wrapped to be in the range of [-180, 180], see GeometryConstants.MIN_LONGITUDE and GeometryConstants.MAX_LONGITUDE
