Implements a tabulated function.
The functor class is based on tabulated arrays tvals and fvals, where tvals contain independent variables and fvals are corresponding function values. Depending on configuration, the function is either interpolated linearly between the tabulated points (type "tabulated-linear" ; default), or yields the last tabulated value until a new tabulated time value is reached (type "tabulated-previous" ).
