/**
 * PHP library for handling cookies.
 * Removed all the static stuff, i prefer instances and DI for handling values and libraries globally
 * I modified it so that the set values will be reflected in the $_COOKIE array in real time and not on page refresh, which solves a lot of problems (especially with authentication).
 * Also i simplified the namespace, since i tend to keep the main libraries on our main namespace
