Expand description
The types here (BedParserStreamingIterator and BedParserParallelStreamingIterator)
process incoming bed-like data and process into bigWig and bigBed files.
BedParserStreamingIterator processes the data serially, checking for out
of order chromosomes. BedParserParallelStreamingIterator, on the other
hand, is more complicated wrapper and will queue up to 4 extra chromosomes
to be processed concurrently.
