 ## Design
 
-A Bloom filter has two parameters: _m_, the number of bits used in storage, and _k_, the number of hashing functions on elements of the set. (The actual hashing functions are important, too, but this is not a parameter for this implementation). A Bloom filter is backed by a [BitSet](https://github.com/willf/bitset); a key is represented in the filter by setting the bits at each value of the  hashing functions (modulo _m_). Set membership is done by _testing_ whether the bits at each value of the hashing functions (again, modulo _m_) are set. If so, the item is in the set. If the item is actually in the set, a Bloom filter will never fail (the true positive rate is 1.0); but it is susceptible to false positives. The art is to choose _k_ and _m_ correctly.

 Given the particular hashing scheme, it's best to be empirical about this. Note
