// 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>.
