- removed some system.out debugging code
- fixed version checking in interval tree
- made indexes store and return a LinkedHashSet for sequence names (to ensure they've preserved the ordering in the file)
- index creators now read the file before creating the index
- changed the Index.write() method to take a LEDataStream instead of a file
- removed the sequence dictionary code on the header
- added utils for getting LEDataStreams
