Module filtering 

Structs

FilterParams

Used to pass around filter options for sketching

Functions

filter_abundance

filter_strands

Filter out kmers that have a large abundance difference between being seen in the “forward” and “reverse” orientations (picked arbitrarily which is which).

guess_filter_threshold

Determines a dynamic filtering threshold for low abundance kmers. The cutoff returned is the lowest number of counts that should be included in any final results.
