Detailed Description

This class is a friend class of HelmholtzEOSMixtureBackend, therefore the static methods contained in it have access to the private and protected variables in the HelmholtzEOSMixtureBackend instance.

In this way the Flash routines can be kept in their own separate file and not pollute the HelmholtzEOSMixtureBackend namespace
