Description
In certain cases, function evaluations is a bottleneck in simulation performance. Therefore, function calls should only get evaluated if necessary. Some of this optimizations are already implemented in the optimization module wrapFunctionCalls. However, there are still function calls which depend on parameter expressions and get evaluated for each simulation step. This is totally unnecessary.

Replying to sjoelund.se:
Can the same be done for discrete-variability functions?
I have that in mind as well. However, that would require different changes and thus it's a different story. I have plans to split the simulation into continuous simulation and discrete simulation which would solve this issue in a nice way.
