:mrdocs:

Return `true` if the specified `numBits` beginning at the specified `index1` in the specified `bitString1` are bitwise equal to the `numBits` beginning at the specified `index2` in the specified `bitString2`, and `false` otherwise. The behavior is undefined unless `bitString1` has a length of at least `index1 + numBits` and `bitString2` has a length of at least `index2 + numBits`.
