/**
 * Services Configuration file.
 *
 * Services are simply other classes/libraries that the system uses
 * to do its job. This is used by CodeIgniter to allow the core of the
 * framework to be swapped out easily without affecting the usage within
 * the rest of your application.
 *
 * This is used in place of a Dependency Injection container primarily
 * due to its simplicity, which allows a better long-term maintenance
 * of the applications built on top of CodeIgniter. A bonus side-effect
 * is that IDEs are able to determine what class you are calling
 * whereas with DI Containers there usually isn't a way for them to do this.
