ConstrainedBidiBFSVisitor: max branches limit (bailout on runaway searches)
connectpairs: progress messages when verbose level >= 2
DBGBloomAlgorithms: fix bug in getStartKmerPos
StringUtil.h: utility convert memory values (e.g. "1.6G") to byte counts
StringUtil.h: minor fixes to SIToBytes
connectpairs: specify bloom filter size in bytes, command line opts for traversal params
connectpairs: more informative progress messages
connectpairs: count failed merges due to inability to find start/goal kmer, return traversal stats from connectPairs method
Use autoconf to check for std::hash
HashGraph: fix iterator-related bug that causes segfaults with libc++
SIToBytes: fix libc++-specific bug ("b" suffix for bytes is no longer allowed)
connectpairs: write unmerged pairs to file, mandatory -o option, fix errors in stats
connectpairs: max mismatches option (-M)
connectpairs: fix broken maxpaths option (-P)
DBGBloom.h: use FastaReader to load bloom filter
Histogram: Don't remove the last entry as noise
