Helper files

If you ask me its more logical to use static functions instead of normal functions, just like you said rand could be for example math -> rand or sort -> rand.

But if I don't use static functions and if I didn't write all of the app I wouldn't know if the function rand is for sorting or for math, if it was static I would be able to call Sort:: and get available helper functions for sorting.

But after all PHP is built in the same way as the helper functions in CI, if you want a random number you call rand() and not Math::rand().
