/**
 * Base PEAR_Exception Class
 *
 * 1) Features:
 *
 * - Nestable exceptions (throw new PEAR_Exception($msg, $prev_exception))
 * - Definable triggers, shot when exceptions occur
 * - Pretty and informative error messages
 * - Added more context info available (like class, method or cause)
 * - cause can be a PEAR_Exception or an array of mixed
 *   PEAR_Exceptions/PEAR_ErrorStack warnings
 * - callbacks for specific exception classes and their children
 *
 * 2) Ideas:
 *
 * - Maybe a way to define a 'template' for the output
 *
 * 3) Inherited properties from PHP Exception Class:
 *
 * protected $message
 * protected $code
 * protected $line
 * protected $file
 * private   $trace
 *
 * 4) Inherited methods from PHP Exception Class:
 *
 * __clone
 * __construct
 * getMessage
 * getCode
 * getFile
 * getLine
 * getTraceSafe
 * getTraceSafeAsString
 * __toString
 *
 * 5) Usage example
 *
 * <code>
 *  require_once 'PEAR/PEAR_Exception.php';
 *
 *  class Test {
 *     function foo() {
 *         throw new PEAR_Exception('Error Message', ERROR_CODE);
 *     }
 *  }
 *
 *  function myLogger($pear_exception) {
 *     echo $pear_exception->getMessage();
 *  }
 *  // each time a exception is thrown the 'myLogger' will be called
 *  // (its use is completely optional)
 *  PEAR_Exception::addObserver('myLogger');
 *  $test = new Test;
 *  try {
 *     $test->foo();
 *  } catch (PEAR_Exception $e) {
 *     print $e;
 *  }
 * </code>

23			/**
24			* Base PEAR_Exception Class
25			*
26			* 1) Features:
27			*
28			* - Nestable exceptions (throw new PEAR_Exception($msg, $prev_exception))
29			* - Definable triggers, shot when exceptions occur
30			* - Pretty and informative error messages
31			* - Added more context info available (like class, method or cause)
32			* - cause can be a PEAR_Exception or an array of mixed
33			* PEAR_Exceptions/PEAR_ErrorStack warnings
34			* - callbacks for specific exception classes and their children
35			*
36			* 2) Ideas:
37			*
38			* - Maybe a way to define a 'template' for the output
39			*
40			* 3) Inherited properties from PHP Exception Class:
41			*
42			* protected $message
43			* protected $code
44			* protected $line
45			* protected $file
46			* private $trace
47			*
48			* 4) Inherited methods from PHP Exception Class:
49			*
50			* __clone
51			* __construct
52			* getMessage
53			* getCode
54			* getFile
55			* getLine
56			* getTraceSafe
57			* getTraceSafeAsString
58			* __toString
59			*
60			* 5) Usage example
61			*
62			* <code>
63			* require_once 'PEAR/PEAR_Exception.php';
64			*
65			* class Test {
66			* function foo() {
67			* throw new PEAR_Exception('Error Message', ERROR_CODE);
68			* }
69			* }
70			*
71			* function myLogger($pear_exception) {
72			* echo $pear_exception->getMessage();
73			* }
74			* // each time a exception is thrown the 'myLogger' will be called
75			* // (its use is completely optional)
76			* PEAR_Exception::addObserver('myLogger');
77			* $test = new Test;
78			* try {
79			* $test->foo();
80			* } catch (PEAR_Exception $e) {
81			* print $e;
82			* }
83			* </code>
