GetSensorGeometry invalid covariant return type error #1

In Openrave 0.9.0, the function 'GetSensorGeometry' is defined as :

virtual SensorGeometryConstPtr GetSensorGeometry(SensorType type=ST_Invalid) = 0;

The SensorGeometryConstPtr type does not correspond with the actual code, defined as a SensorGeometryPtr, causing a "invalid covariant return type" error. To fix this i changed the definition of the function at forceSensor.h to:

virtual SensorGeometryConstPtr GetSensorGeometry(SensorType type);

PD: Thanks to @jgvictores for the help!
