// The main implementation detail in using this smart pointer of a type is to customise the code generated
// to use a pointer to the smart pointer of the type, rather than the usual pointer to the underlying type.
// So for some type T, shared_ptr<T> * is used rather than T *.
// shared_ptr namespaces could be boost or std or std::tr1
// For example for std::tr1, use:
// #define SWIG_SHARED_PTR_NAMESPACE std
