Description
...........

Simple check for primer sequences in sequencing data. The tool counts the number
of occurrences of the primer sequence, its complement, the reverse and the
reverse complement.

See also: https://benjjneb.github.io/dada2/ITS_workflow.html#identify-primers

Usage
.....

**Input** FASTQ datasets and forward and reverse primers

**Output** a table listing the counts of the different occurrences in the read files.
