  36  * ----------------------------------
  37  * 1.6.0
  38  *  - This class loader is now 100% singleton, no other instance is really
  39  *    required, therefore the factory method can be removed safely
  40  *  - renamed initLoader() to initClassLoader()
  41  *  - An instance of a FrameworkConfiguration is no longer set here as this
  42  *    violated the rule that there shall be no instance set of that class
  43  *  - .htaccess is marked as deprecated as this should be no longer done
  44  *  - scanClassPath() is now protected, please use other scan*() methods
  45  * 1.5.0
  46  *  - Namespace scheme Project\Package[\SubPackage...] is fully supported and
  47  *    throws an InvalidArgumentException if not present. The last part will be
  48  *    always the class' name.
  49  * 1.4.0
  50  *  - Some comments improved, other minor improvements
  51  * 1.3.0
  52  *  - Constructor is now empty and factory method 'createClassLoader' is created
  53  *  - renamed loadClasses to scanClassPath
  54  *  - Added initLoader()
  55  * 1.2.0
  56  *  - ClassLoader rewritten to PHP SPL's own RecursiveIteratorIterator class
  57  * 1.1.0
  58  *  - loadClasses rewritten to fix some notices
  59  * 1.0.0
  60  *  - Initial release
