IDAS DAE system that contains information on residual equation functor, sensitivity residual equation functor, as well as initial conditions.
This is a base type that is intended to contain common values used by forward sensitivity system.
| F | type of functor for DAE residual |
| Tyy | scalar type of initial unknown values |
| Typ | scalar type of initial unknown's derivative values |
| Tpar | scalar type of parameters |
