/**
 * A simple class loader that deals with the Framework classes and is intended
 * for use with unit tests executed by PHPUnit.
 *
 * PHPUnit offers the possibility to use a "bootstrap" file with every test.
 *
 * This file can be used and will register a simple autoloader so that the files
 * used in the tests can be found.
 *
 * To use PHPUnit with Netbeans create a folder to be used as project test folder
 * and populate it with something like
 *  for i in `ls ../Packages/Framework/` ;
 *    do ln -s ../Packages/Framework/$i/Tests/Unit $i ;
 *  done
 *
 * @param string $className
 * @return void
