//This file introduces the timer_x_args function.
//It accepts a function with no arguments as a parameter.
//to add arguments, simply insert them into timeAFunction, and
//then into t();
//For Example:
//std::chrono::duration<double> timeAFunction(int a, double b,T t){
//t(a, b);
//on the appropriate lines


//since it returns a duration<double> the easiest way to stream this is to use
//the .count() method.
//For Example (in a different source file):
//auto funcTime = timer_no_args(function);
//std::cout << funcTime.count() << std::endl;
