                      Ramachandran


Calculate the Phi and Psi torsions for selected atoms.

Usage example:

  ana = Ramachandran(msys_model, cms_model, 'protein and res.num 20-30')
  results = analyze(tr, ana)

where C{tr} is a trajectory, and C{results} is a C{list}, and each element
in the C{list} is a C{list}: [(phi_0, psi_0), (phi_1, psi_1),] for the
corresponding trajectory frame.
