// class G4SolidStore
//
// Class description:
//
// Container for all solids, 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
// G4SolidStore::GetInstance().
//
// All solids should be registered with G4SolidStore, and removed on their
// destruction. Intended principally for UI browser. The underlying
// container initially has a capacity of 100.
//
// If much additional functionality is added, should consider containment
// instead of inheritance for std::vector<T>
//
// Member data:
//
// static G4SolidStore*
//   - Ptr to the single G4SolidStore

// History:
// 18.04.01 G.Cosmo Migrated to STL vector
// 10.07.95 P.Kent  Initial version
