Cross-platform infinity and not-a-number routines.
Warning: if INFINITY is not defined as a constant, this uses the STL numeric_limits<T>::infinity() call. Global static members set to Inf will NOT necessarily be initialized properly on certain platforms, e.g., Windows. The solution is to avoid declaring static variables equal to infinity.
