Returns the output value from the noise module given the
(latitude, longitude) coordinates of the specified input value
located on the surface of the sphere.
@param lat The latitude of the input value, in degrees.
@param lon The longitude of the input value, in degrees.
@returns The output value from the noise module.
@pre A noise module was passed to the SetMod() method.
This output value is generated by the noise module passed to the
SetMod() method.
Use a negative latitude if the input value is located on the
southern hemisphere.
Use a negative longitude if the input value is located on the
western hemisphere.
