Quotient-space projections of a supercell eigenvector

[ExpHP]

• [ ] Implementation
  • [ ] Given supercell q, superstructure, supercell matrix that produced it, and a supercell eigenvector, provide probabilities associated with each quotient space Q for each vi
  • [x] Find all the Q vectors (trivial if we restrict ourselves to HNF supercell mats)
    • although that limitation should be checked (is_hnf)
    • actually, let's cheese it even further. Diagonal only.
    • actually not so trivial because FBZ is centered around gamma. Cases for even and odd n look different. Gross.
    • we're going to need weights to handle boundary points.
  • [x] Selection of sampling points within an FBZ (easy for "fast" (parallelepiped) FBZ, not sure about true (voronoi) FBZ)
    • [x] gamma only for now
  • [ ] Summation over labeled quantities
    • [ ] label by metadata and cartesian axis
  • [ ] Once that is working, factor out things that don't depend on the eigenvector so we can have a fast method of doing many eigenvectors at once
• [ ] Wrapper executable
• [ ] Call on all existing data
