requires
- 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()
