[1] upgraded buffered iterator to have unbounded lookahead

[2] down-graded some custom iterators that could not implement this
behavior (compatible because the signatures only indicate Iterator)

[3] added RollBackIterator for iterators that can be backed up (useful
for scanning)

[4] DefaultBufferedIterator for a nice default implementaiton of
BufferedIterator

[5] Added RandomAccessSeq for Seq's that can be indexed in linear time
(e.g., Array), optimized seq methods for these seqs. Got the appropriate
classes to inherit from this trait

[6] Enhanced projections so they are iterables. An operation on a
projection is also a projection (if possible)

[7] Various small enhancements to the JCL
