Detailed Description

template<class T>
class SGRawValuePointer< T >

This is the most efficient way to tie an external value, but also the most dangerous, because there is no way for the supplier to perform bounds checking and derived calculations except by polling the variable to see if it has changed. There is no default constructor, because this class would be meaningless without a pointer.
