struct OETorsion

An object to contain the information necessary to represent a torsion: a 3D rotation around the vector defined by the coordinates of a2 and a3 and an angle defined by a1 and a4. The angle is stored in radians instead of degrees


OETorsion(OEAtomBase *a1, OEAtomBase *a2, OEAtomBase *a3, OEAtomBase *a4,
          double rads)

Construct a torsion object containing 4 atoms and an angle in radians.
