//+ Name DwBoyerMoore -- Class for executing Boyer-Moore string search algorithm
//+ Description
//. {\tt DwBoyerMoore} implements the Boyer-Moore algorithm for searching
//. for a string. The Boyer-Moore algorithm is fast, but requires a bit
//. of start-up overhead compared to a brute force algorithm.
