Detailed Description

template<class T, bool is_ref_counted = type::cond::is_base_of<ref_counted,T>::value>
class cgv::data::ref_ptr< T, is_ref_counted >

reference counted pointer, which can work together with types that are derived from ref_counted, in which case the reference count of ref_counted is used. Otherwise a reference count is allocated and access to the stored instance needs to follow two pointers.
