 - 0 <= frac <= 1
 - T must be an array type such as dlib::array or std::vector
 ensures
 - This function takes the elements of a and splits them into two groups. The
 first group remains in a and the second group is put into b. The ordering of
 elements in a is preserved. In particular, concatenating #a with #b will
 reproduce the original contents of a.
 - The elements in a are moved around using global swap(). So they must be
 swappable, but do not need to be copyable.
 - #a.size() == floor(a.size()*frac)
 - #b.size() == a.size()-#a.size()
