class  CoupledSwitchingTimeDerivative
 This kernel adds a contribution \( \left( \frac{\partial F_a}{\partial \eta_{ai}} f_a + \frac{\partial F_b}{\partial \eta_{ai}} f_b + ... \right) \frac{\partial \eta_{ai}}{\partial t} \) where \( a,b,.. \) are the phases, \( h_a, h_b,.. \) are the switching functions, \( \eta_{ai} \) is the order parameter that is the nonlinear variable, \( t \) is time, and \( F_a, F_b,.. \) are functions for each phase.
