c2x futures

What changes are expected in future versions of c2x? TCM is used as a test-bed for new features before they make a public release. Sometimes features currently in development are listed below:

c2x 2.30 will support:

• Reading of Quantum Espresso's wavefunction files (no spinors)
• Reading of Abinit's WFK files
• Reading of VASP's WAVECAR files (no spinors)
• Simple ways of adding vacuum (including when creating surfaces)
• Calculation of integral of |spin| (useful for antiferromagnets, where integral of spin will be zero)
• Simple option for simple tiling when creating supercells, e.g. -x=1x1x2 for a 1x1x2 supercell

Along with improvements to the choice of new grid when moving 3D data between different cells, and various minor changes.
