//From http://www.richelbilderbeek.nl/CppGetDifference.htm

template <typename T>

const std::vector<T> GetDifference(

  const std::vector<T>& a,

  const std::vector<T>& b)

{

  assert(a.size()==b.size());

  std::vector<T> v(a);

  const std::size_t sz = v.size();

  for (std::size_t i = 0; i!=sz; ++i)

  {

    v[i]-=b[i];
