matrix multiplication, Strassen algorithm

Description

This is a library written in C++98 (actually it is a C++ class). It implements fast algorithm for matrix multiplication. The library implements the Strassen algorithm. The asymptotic complexity of the Strassen algorithm is O(n^2.80735). The naive algorithm has O(n^3). Strassen algorithm is faster for matrices with sizes from 32.
