// Class description:
//
// Container for all physical volumes, 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
// G4PhysicalVolumeStore::GetInstance()
//
// All volumes should be registered with G4PhysicalVolumeStore, and removed on
// their destruction. The underlying container initially has a capacity of 100.
// A map indexed by volume names is also recorded for fast search;
// pointers to volumes with same name are stored in buckets.
//
// If much additional functionality is added, should consider containment
// instead of inheritance for std::vector<T>.
