/**
 * CI_BASE - For PHP 4
 *
 * This file is used only when CodeIgniter is being run under PHP 4.
 *
 * In order to allow CI to work under PHP 4 we had to make the Loader class
 * the parent of the Controller Base class.  It's the only way we can
 * enable functions like $this->load->library('email') to instantiate
 * classes that can then be used within controllers as $this->email->send()
 *
 * PHP 4 also has trouble referencing the CI super object within application
 * constructors since objects do not exist until the class is fully
 * instantiated.  Basically PHP 4 sucks...
 *
 * Since PHP 5 doesn't suffer from this problem so we load one of
 * two files based on the version of PHP being run.
