- fixed a byte packing bug related to having exactly 7 bits of octal data
where we weren't correctly packing the last bit and moving the byte count
forward. This resulted in bogus colors being written
- fixed a bug for points that exactly match an octet boundary test creating
voxels that are one a unit smaller than they should be
- added outputBufferBits() which will output an entire buffer as debug bits/bytes
- tweak to outputBits() to allow caller to ask for NewLine or not
- added insertIntoSortedArrays() which keeps a set of arrays sorted by a key
