Compare k-mer sets

1	kmr_compare(in_files, cmp, ci = 2, cx = 1e+09, cs = 255)

`in_files`	list of named file paths. The names are to be used in the comparison string.
`cmp`	a list containing a single named string with the kmer operations using the file short names.
`ci`	integer; min k cutoff value; default 2.
`cx`	integer; max k cutoff value; default 1e9.
`cs`	integer; max k count value; default 255.

The in_files list strings may contain parameter values for each in_file after the path.

Shorthand operator definitions: * intersect - subtract ~ counters_subtract + union

Highest priority: *. All other operators have equal priority.

Counter calculation modes are available for the oerators: *, ~, +. They are: min, max, diff, sum, left, right
