* \brief A fluid system for two-phase models assuming immiscibility and
* thermodynamic equilibrium
*
* The wetting and the non-wetting phase can be defined individually
* via <tt>Opm::LiquidPhase<Component></tt> and
* <tt>Opm::GasPhase<Component></tt>. These phases consist of one pure
* component. With the help of this adapter class, the phase
* properties can be accessed. This is suitable for pure two-phase
* systems without compositional effects.
