Object node controller

The object-node-controller module is a module that allows you to select an object in the environment thanks to its id, as well as to move it, orient it and modify its scale (homothety factor). The list of objects that can be selected is stored in an xml file in the Environment folder; for example the file bin\Environments\Empty.xml contains only one chair:

In the interface we also have a "sliding_object" checkbox that will drag the object from left to right in the scene and send gaze signals to GRETA so that an agent follows the moving object with its eyes.
