+We also provide a method for a quick boolean check of whether two hexadecimal strings
+are within a given Hamming distance.

+
+Similarly, ``hexhamming`` supports byte arrays via ``check_bytes_arrays_within_dist``, which has
+a similar API as ``check_hexstrings_within_dist``, except it expects a byte array. Additionally,
+it will check if any element of a byte array is within a specified Hamming Distance of another
+byte array.
