* Changed convert2cfg.m to do it's basis vector calculations in degrees. Kept all other calculations involving alpha, beta, and gamma in radians (for now) by refactoring the variables to alphar, betar, and gammar, respectively.
    * This prevents very small values arising from (I think) floating point rounding errors in the degree -> radian conversion
    * My initial tests show that it's writing the CFG file correctly now (testing with the BaTiO3 cell and my own 4H-SiC and a-SiO2 data)
