assumes:
- solvent is immiscible in the oil phase
- gas pvt and relperms are used for the solvent
- no initial solvent in the model
Solvent is injected using the WSOLVENT keyword
TODO: Make it possible to change WSOLVENT
The current implementation avoids the using of formEllipticSystem() and
vercatCollapseJacs(), which take a significant amount of computing time
during the non-linear solutions.
For g++-4.4 support for nullptr is not complete. Using it
to initialize an empty shared_ptr breaks compilation:

Here the DUNE's nullptr implementation is used with std::shared_ptr which are not
compatible.
We fix this by using the emptry constructor of std::shared_ptr to create a nullptr.
