-/**
- * ReadErrorRateWalker assesses the error rate per read position ('cycle') by comparing the
- * read to its home on the reference and noting the mismatch rate.  It ignores reads with
- * indels in them, treats high and low-quality references bases the same, and does not count
- * ambiguous bases as mismatches.  It's also thread-safe, so you can process a slew of reads
- * in short order.
