Does boost (or any other lib in C++) have facility to support smth that 
resembles hierarchical enumeration? I would like to have something like the 
following:

enum Hierarchy
{
   Store::Clothing = 1
   Store::Electronics,
   Building::Residential,
   Building::Commercial
}

...
Hierarchy h = Hierarchy::Building::Commercial;
...
if (h == Hierarchy::Store)
{
   if (h == Hierarchy::Store::Clothing)
      std::cout<<"clothing";
}
...
