Updated readme
Fixed mat2x4 value-type constructor

#include <glm/glm.hpp>
#include <iostream>
using namespace std;
int main() {
    // creating two should-be identical matrices
  glm::mat2x4 A((int)1);
  glm::mat2x4 B((float)1);

  float* Aptr = (float*)&A;
  float* Bptr = (float*)&B;
  for(int i = 0 ; i < 8 ; i++) cout << Aptr[i] << " ";  cout << endl;
  for(int i = 0 ; i < 8 ; i++) cout << Bptr[i] << " ";
}
