[case] Function

A function property defined by mathematical expression. For the evaluation of the expressions the exprtk library is used. In the expressions all variables defined in MaterialPropertyLib::Variable enum, t for time, x,y,z for the spatial position are supported, and curves from the <curves> section can be called using their names. A curve is a single argument function and can be used in an expression like curveA(sin(t)).

The evaluation is thread-safe for OpenMP by using per-thread storage.
