// The RTI::Value class is used to as a generic value holder that contains a
// pointer to the memory location and the size of the value.  This class is
// used for attributes, parameters, and user supplied tags.  The constructor
// takes a pointer to the data value and the size of the data.  The key methods
// on this class is the data method which returns a constant pointer to the
// value memory location, and the size method which returns the size in bytes
// of the value.  The templatized class ValueImplementationType provides RTI
// implementations the ability to customize their particular implementation.
// The int template type parameter provides the ability to support strong
// typing.
