4.1 Constructor attributes (keyword __init__xattributes_

The keyword __init__xattributes__ must contains a list of XAttribute's. This keyword allows to define the constructor of the class. You can access each attribute directly by its name or by get and set methods. For instance, if an xattribute has name internal_radius, you can access it by internal_radius, getInternalRadius and setInternalRadius. For instance:
