This function handles the evaluation of the objective function in spot.
This includes handling of the random number generator stream as well as the actual evaluation.

noise = FALSE, ...)matrix of already known solutions, to determine whether RNG seeds for new solutions need to be incremented.
matrix of new solutions.
objective function to evaluate the solutions in xnew.
initial seed to be used for the random number generator seed. Set to NA to avoid using a fixed seed.
parameter specifying whether the target function is noisy.
parameters passed to fun.
the matrix ynew, which are the observations for fun(xnew)
