* Adds an additional class repository.
*
* Used for adding class repositoryies outside the eZ components to be
* loaded by the autoload system.
*
* This function takes two arguments: $basePath is the base path for the
* whole class repository and $autoloadDirPath the path where autoload
* files for this repository are found. The paths in the autoload files are
* relative to the package directory as specified by the $basePath
* argument. I.e. class definition file will be searched at location
* $basePath + path to the class definition file as stored in the autoload
* file.
*
* addClassRepository() should be called somewhere in code before external classes
* are used.
*
* Example:
* Take the following facts:
* <ul>
* <li>there is a class repository stored in the directory "./repos"</li>
* <li>autoload files for that repository are stored in "./repos/autoloads"</li>
* <li>there are two components in this repository: "Me" and "You"</li>
* <li>the "Me" component has the classes "erMyClass1" and "erMyClass2"</li>
* <li>the "You" component has the classes "erYourClass1" and "erYourClass2"</li>
* </ul>
*
* In this case you would need to create the following files in
* "./repos/autoloads". Please note that the part before _autoload.php in
* the filename is the first part of the <b>classname</b>, not considering
* the all lower-case letter prefix.
*
* "my_autoload.php":
* <code>
* <?php
* return array (
* 'erMyClass1' => 'Me/myclass1.php',
* 'erMyClass2' => 'Me/myclass2.php',
* );
* ?>
* </code>
*
* "your_autoload.php":
* <code>
* <?php
* return array (
* 'erYourClass1' => 'You/yourclass1.php',
* 'erYourClass2' => 'You/yourclass2.php',
* );
* ?>
* </code>
*
* The directory structure for the external repository is then:
* <code>
* ./repos/autoloads/my_autoload.php
* ./repos/autoloads/you_autoload.php
* ./repos/Me/myclass1.php
* ./repos/Me/myclass2.php
* ./repos/You/yourclass1.php
* ./repos/You/yourclass2.php
* </code>
*
* To use this repository with the autoload mechanism you have to use the
* following code:
* <code>
* <?php
* ezcBase::addClassRepository( './repos', './repos/autoloads' );
* $myVar = new erMyClass2();
* ?>

*
* @throws ezcBaseFileNotFoundException if $autoloadDirPath or $basePath do not exist.

/**
* Provides a method to implement delayed initialization of objects.
*
* With the methods in this class you can implement callbacks to configure
* singleton classes. In order to do so you will have to change the
* getInstance() method of your singleton class to include a call to
* ezcBaseInit::fetchConfig() as in the following example:
*
* <code>
* <?php
* public static function getInstance()
* {
* if ( is_null( self::$instance ) )
* {
* self::$instance = new ezcConfigurationmanager();
* ezcBaseInit::fetchConfig( 'ezcInitConfigurationManager', self::$instance );
* }
* return self::$instance;
* }
* ?>
* </code>
*
* You will also need to configure which callback class to call. This you do
* with the ezcBaseInit::setCallback() method. The following examples sets the
* callback classname for the configuration identifier
* 'ezcInitConfigurationManager' to 'cfgConfigurationManager':
*
* <code>
* <?php
* ezcBaseInit::setCallback( 'ezcInitConfigurationManager', 'cfgConfigurationManager' );
* ?>
* </code>
*
* The class 'cfgConfigurationManager' is required to implement the
* ezcBaseConfigurationInitializer interface, which defines only one method:
* configureObject(). An example on how to implement such a class could be:
*
* <code>
* <?php
* class cfgConfigurationManager implements ezcBaseConfigurationInitializer
* {
* static public function configureObject( ezcConfigurationManager $cfgManagerObject )
* {
* $cfgManagerObject->init( 'ezcConfigurationIniReader', 'settings', array( 'useComments' => true ) );
* }
* }
* ?>
* </code>
*
