Detailed Description
template<class T>
class gtsam::internal::ExpressionNode< T >
Expression node. The superclass for objects that do the heavy lifting An Expression<T> has a pointer to an ExpressionNode<T> underneath allowing Expressions to have polymorphic behaviour even though they are passed by value. This is the same way boost::function works. http://loki-lib.sourceforge.net/html/a00652.html
