Check option

[drchriscole]

Like for the std md5sum command it would be really handy to have a 'check' option (-c) in order to check a fastq/bam vs it's bamhash to programmatically verify it's consistency.

Also, it's confusing that fastq read pairs are only counted once whereas they're counted twice in the bam. It would be clearer if the numbers agreed as well as the hashes. Thanks!
