* Massive update to abinit support. Note that pymatgen.io.abinitio has
been refactored to pymatgen.io.abinit. (Matteo, Setten)
* NwOutput now supports parsing of Hessian matrices (contributed by Xin
Chen)
* Gaussian support now has the ability to read potential energy surface
and electronic transitions computed with TD-DFT (Germain Salvato
Vallverdu)
* Bug fixes for CifWriter with symmetry.
* Bug fixes for surface generation and reactions.
* Monty requirement increased.
