/**
 * This class contains all main TypoScript features.
 * This includes the rendering of TypoScript content objects (cObjects).
 * Is the backbone of TypoScript Template rendering.
 *
 * There are lots of functions you can use from your include-scripts.
 * The class is normally instantiated and referred to as "cObj".
 * When you call your own PHP-code typically through a USER or USER_INT cObject then it is this class that instantiates the object and calls the main method. Before it does so it will set (if you are using classes) a reference to itself in the internal variable "cObj" of the object. Thus you can access all functions and data from this class by $this->cObj->... from within you classes written to be USER or USER_INT content objects.
