`desired-m``P``N``#!optional``K`procedureCalculates a near-optimal number of bits of discrimination to meet the desired probability of false positives

`P`, with the given population size`N`and number of hashes`K`. When the`K`parameter is missing`optimum-k`is used to calculate a value.A multi-valued return of the calculated

`M`,`K`, and`P`values. The calculated probability may be lower than the desired. The calculated`M`value will always be a fixnum.
