a bug in the printing of the band path to Phoebe's output file
proper ignoring of comments coming after a # character in input files
simplification of bands_app output. Now, when two consecutive high symmetry points with the same name are given in the input file, even if they have different coordinates, the high sym band path indices output for those two points will be the same. This means we can also accordingly remove a slightly convoluted fix for this that was sometimes causing issues in our bands plot script.
