def measure_params.compute_angle (   v1,
  v2 
)
calculates the angle between two vectors.
v1 and v2 are array objects.
returns a float containing the angle in radians.

def measure_params.compute_squared_dist (   coord1,
  coord2 
)
compute the squared distance between two xyz vector (3D).

def measure_params.compute_torsion (   v1,
  v2,
  v3,
  v4 
)
Returns a float value for the dihedral angle between
the four vectors. They define the bond for which the
torsion is calculated (~) as:
V1 - V2 ~ V3 - V4
