Dynaphopy

Fixed a critical error in the new derivative calculation function that made an incorrect velocity scaling.

OSX compatibility fixes
Restructure of the project directories
Code simplification

Minor changes

Interactive interface for renormalized phonon dispersion
Small changes in the names of some functions related to renormalized phonon dispersion
Bug fixes

New integration with phonopy: calculate phonopy renormalized force_sets file for finite temperature calculations.
Calculation of new phonon properties: Kinetic energy, ocupation number
Now dynaphopy also reads trajectories from LAMMPS code.
New tools for saving and loading and manipulating velocity data using hdf5 files. (for saving huge use of memory).
Improved atomic displacements calculation algorithm
Other minor fixes and imporvements

Added atom displacement calculation
