// class G4AssemblyStore
//
// Class description:
//
// Container for all assemblies, with functionality derived from
// std::vector<T>. The class is a `singleton', in that only
// one can exist, and access is provided via the static method
// G4AssemblyStore::GetInstance().
//
// All assemblies should be registered with G4AssemblyStore, and removed on
// their destruction. The underlying container initially has a capacity of 20.
//
// If much additional functionality is added, should consider containment
// instead of inheritance for std::vector<T>
//
// Member data:
//
// static G4AssemblyStore*
//   - Pointer to the single G4AssemblyStore
 
// History:
// 9.10.18 G.Cosmo Initial version
