A virtual function to get the derivative of the state. This is useful for things like fat link states, where the derivative of the state with respect to the thin links is complicated. The default implementation just multiplies the accumulated force by the (thin) links, which works because 
and the pi momenta get factored out this function modifies the force term
Reimplemented in Chroma::StoutGaugeState< P, Q >, Chroma::SLICFermState< T, P, Q >, Chroma::StoutFermState< T, P, Q >, and Chroma::HexFermState< T, P, Q >.

Return the amorphous BC object for this state.
The user will supply the BC in a derived class
