= Overview=
* All slots/property of QObject are automatically exposed to the python interpreter
* Concept of decorator
** Expose regualar cpp method of QObject 
** Expose object and method of pure cpp classes
* Complete wrapping of all Qt Classes
* See http://pythonqt.sourceforge.net/

= Implementation =
* CTK Layer 
** qCTKConsoleWidget 
** qCTKShellPython
** qCTKAbstractPythonManager: 
*** registerPythonQtDecorator, registerClassForPythonQt, registerCPPClassForPythonQt, executeString, getVariable, executeFile, ...
*** also virtual methods: pythonPaths and preInitialization

* Concrete example
** Slicer superbuild download and patch SVN PythonQt head
** Slicer CMake script pre-compile all slicer .py class
** VTK all wrapped in python and exposed
** qSlicerPythonManager
<pre>
void qSlicerPythonManager::preInitialization()
{
  Superclass::preInitialization();

  // Register decorators
  this->registerPythonQtDecorator(new qSlicerBaseQTBasePythonQtDecorators(this));

  qSlicerCoreApplication* app = qSlicerCoreApplication::application();

  // Add object to python interpreter context
  this->addObjectToPythonMain("_qSlicerCoreApplicationInstance", app);

  // Evaluate application script
  this->executeFile(app->slicerHome() + "/bin/Python/slicer/slicerqt.py");
