Description:

 """Rotates every atom in the AMPAL object. Parameters angle : float Angle that AMPAL object will be rotated. axis : 3D Vector (tuple, list, numpy.array) Axis about which the AMPAL object will be rotated. point : 3D Vector (tuple, list, numpy.array), optional Point that the axis lies upon. If `None` then the origin is used. radians : bool, optional True is `angle` is define in radians, False is degrees. inc_alt_states : bool, optional If true, will rotate atoms in all states i.e. includes alternate conformations for sidechains.
