The main goal of this project is to provide easy access to semiconductor
band parameters for calculations and simulations. Basic functionality
requires only the standard python distribution.

Example scripts are provided for basic usage and for generating common
plots such as bandgap vs. lattice constant and bandgap vs. alloy
composition.

Materials included in this version:
- III-V Zinc Blendes
    - Binaries
        - AlN, GaN, InN,
          AlP, GaP, InP,
          AlAs, GaAs, InAs,
          AlSb, GaSb, InSb
    - Ternaries
        - AlGaN, AlInN, GaInN,
          AlGaP, AlInP, GaInP,
          AlGaAs, AlInAs, GaInAs,
          AlGaSb, AlInSb, GaInSb,
          AlNP, GaNP, InNP,
          AlNAs, GaNAs, InNAs,
          AlPAs, GaPAs, InPAs,
          AlPSb, GaPSb, InPSb,

          AlGaInN, AlGaInP, AlGaInAs, AlGaInSb,
          AlGaNP, AlInNP, GaInNP,
          AlGaNAs, AlInNAs, GaInNAs,
