LatLngBounds.from() validation

[osana]

LatLngBounds(double, double, double,double) constructor does not validate its parameters.

should northLatitude >= southLatitude and eastLongitude >= westLongitude?
Should we through and IAE?

Should we compare agains GeoConstants Max, Min values?
Should use the Max, Min or throw IAE if that is not the case?

If values are passed in as wrapped? Do change into non-wrapped or do we min/max?

LatLngBounds constructor is package private. It is used by LatLngBounds.Builder() and by LatLngBounds.from() method. Builder does parameter validation while LatLngBounds.from() does not.

The same parameter validation should be added as is done in the Builder via LatLng() constructor. See LatLng's setLatitude() and setLongitude() methods.
New tests should be added to LatLngBoundsTest as are done in LatLngTest - see Constructor tests.
