### The model can now be used with either mole or mass fractions. The property

useMoles has to be set in the problem file and the boundary conditions
have to be choosen accordingly.

In order to be consistent with the multicomponent models (3p3c,
3p3cni,...) the model uses MOLE fractions by default now.

The documentation is changed and extended accordingly.
