* Include for PEAR_Error and PEAR classes
* This class is for objects where you want to separate the code for
* some methods into separate classes. This is useful if you have a
* class with not-frequently-used methods that contain lots of code
* that you would like to avoid always parsing.
* The PEAR_Autoloader class provides autoloading and aggregation.
* The autoloading lets you set up in which classes the separated
* methods are found. Aggregation is the technique used to import new
* methods, an instance of each class providing separated methods is
* stored and called every time the aggregated method is called.
