Code registry

The code registry engine.

Drupal maintains an internal registry of all functions or classes in the system, allowing it to lazy-load code files as needed (reducing the amount of code that must be parsed on each request). The list of included files is cached per menu callback for subsequent loading by the menu router. This way, a given page request will have all the code it needs but little else, minimizing time spent parsing unneeded code.
