This function defines the standard gravity fields for the World object.
| gravityType | gravity [m/s2] | description |
| Types.GravityType.NoGravity | = {0,0,0} | No gravity |
| Types.GravityType.UniformGravity | = g | Constant parallel gravity field |
| Types.GravityType.PointGravity | = -(mu/(r*r))*r/|r| | Point gravity field with spherical mass |
