// 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. The underlying container initially has a capacity of 100.
// A map indexed by solid names is also recorded for fast search;
// pointers to solids with same name are stored in buckets.
//
// If much additional functionality is added, should consider containment
// instead of inheritance for std::vector<T>.
