// RDValue does not dynamically create POD types (kind of like
//  cdiggins::any)  However, it doesn't use RTTI type info
//  directly, it uses a companion short valued type
//  to determine what to do.
// For unregistered types, it falls back to boost::any.
//  The Size of an RDAny is (sizeof(double) + sizeof(short) == 10 bytes)
//
//   For the sake of compatibility, errors throw boost::bad_any_cast
//
// Examples:
//
//   RDAny v(2.);
//   v = 1;
//   std::vector<double> d;
//   v == d;
//   v.asDoubleVect().push_back(4.)
//   rdany_cast<std::vector<double>(v).push_back(4.)
//
//   Falls back to boost::any for non registered types
//   v = boost::shared_ptr<ROMol>(new ROMol(m));
//
