Detailed Description

template<class Derived, typename T>
class CTXStateElement< Derived, T >

CTXStateElement is like CTXSpaceElement but subscribe to the stack for connection open and close events

The child must implement : bool new_flow(T*, Packet*); void push_flow(int port, T*, Packet*); void release_flow(T*);

This is the equivalent to FlowStateElement but use the last Stack element to manage the state instead of relying on timeout/looking at the packet to learn about a closing state
