public interface SecondaryEquations
In some cases users may need to integrate some problem-specific equations along with a primary set of differential equations. One example is optimal control where adjoined parameters linked to the minimized hamiltonian must be integrated.
 This interface allows users to add such equations to a primary set of first order differential equations
 thanks to the ExpandableStatefulODE.addSecondaryEquations(SecondaryEquations)
 method.
