Pymatgen

* Major bug fixes for CIF parsing (Will Richards).
* Support for {Li,Na} syntax in parse_criteria for MPRester.
* Additional example notebook for ordering and enumeration.
* More robust checking for oxidation states in EnumerateStructureTRansformation.
* Improvements to Slab polarity checking.

* Massive update to abinitio (Matteo).
* Improvements to OUTCAR parsing (Ioannis Petousis).

* Powerful Slab generation algorithms (beta!).
* Improvements to DiffusionAnalyzer with constant smoothing option.
* Significantly improve look of DOS plots using prettyplotlib.

* Cost analysis module (Anubhav Jain)
* More Py3k fixes.
* Extensive abinitio updates (Matteo).

* Completely revamped symmetry package. The finder.SymmetryFinder and
pointgroup and spacegroup modules are now deprecated. Instead,
all symmetry analysis is in the :module:`pymatgen.symmetry.analyzer`_
module. There is also a completely rewritten support for symmetry groups in
:module:`pymatgen.symmetry.groups`_. Structure now supports a static
constructor to generate a structure from a spacegroup (see examples).
* BatteryAnalyzer class (Anubhav Jain) to provide for some common analysis of
intercalation electrodes.
* Minor bug fixes for structure_matcher, lattice, abinitio.
* MOAB qadapter for abinit. (Liam Damewood)

* Fix missing structures json data.
