Type handling is mainly done using templates. Template Slic3r::ClassTraits is used to store info about exported types (perl class name). Currently only perl class name and refference name is used. Template values are initialized by REGISTER_CLASS macro. This macro is used in .cpp file of class ( it needs to be used exactly for each type). Ref<type> class is used to return value as perl reference. Operator overloading is used to make c++ and XSpp happy, only pointer value should be possible to return. Clone<type> class is used to return copy of value ( using new and copy constructor). Copy is created on assigment, this should be probably improved (memory leak on multiple assignments). It is overloaded to be able to return type, type* and type&. Typechecking in ExtrusionEntityCollection updated to check all passed types.
