Implement GreedyMotifSearch

Given: Integers k and t, followed by a collection of strings Dna.

Return: A collection of strings BestMotifs resulting from running GreedyMotifSearch(Dna, k, t). If at any step you find more than one Profile-most probable k-mer in a given string, use the one occurring first.
