StackAllocator controls the memory allocation/deallocation of Minuit.
If MN_NO_THREAD_SAVE is defined, memory is taken from a pre-allocated piece of heap memory which is then used like a stack, otherwise via standard malloc/free. Note that defining MN_NO_THREAD_SAVE makes the code thread- unsave. The gain in performance is mainly for cost-cheap FCN functions.
