Return a function which counts its function evaluations.
This is a counting wrapper for a smoof_function, i.e., the returned function
first checks whether the given argument is a vector or matrix, saves the
number of function evaluations of the wrapped function to compute the function
values and finally passes down the argument to the wrapped smoof_function.
