static int compare(const T *seq1, const T *seq2, size_t cnt)
Sequence comparison.
Compares the first cnt number of elements in the two sequences seq1 and seq2, returns negative/0/positive if seq1 is less/equal/greater than seq2.
Following are char_traits funcitons, which make this class char_traits compatiable, so that it can be used in std::basic_string template, and be manipulated by the c++ stl algorithms.
