Follow the change of tensor3_rotation in fc3.c after the tag v0.9.0. This may induce bug.
Segmentation fault when fc3 is huge. The reason is not clear. To prepare a new clean numpy array and then to copy to it worked. This requires twice large memory space. In addition, for large fc3 case, memory leak-like behavior was found (numpy 1.8.1-ubuntu). Memory usage constantly increases during distributing fc3.
When number of displacements for 1st atom is greater than 1, it didn't work. Fixed.
Update spglib for Py3k compatibility.
More fixes for PyInt and PyString.
Merge branch 'master' of https://github.com/materialsvirtuallab/phonopy into python3
Taking care of python 2.5 or before
Improve trim_cell using numpy routines
Symmetry::_set_map_operations() is called only when needed, because this method is the bottle neck of creating Symmetry object and _map_operations is rarely used.
Minor modification
Fix file output bug
Set version as 1.9.1
