   * @test validate the equality and order relations of 
   *       Asset::Ident and Asset objects.
   * @note a known problem is that only Asset smart ptrs
   *       are supported for comparison, not smartpointers
   *       of Asset subclasses. To solve this, we would
   *       either have to repeat the operator definitions,
   *       or resort to template metaprogramming tricks.
   *       Just providing templated comparison operators
   *       would generally override the behaviour of 
   *       std::shared_ptr, which is not desirable.
