-//(1) Complete the collatz function below. It should
-//    recursively calculate the number of steps needed 
-//    until the collatz series reaches the number 1.
-//    If needed you can use an auxilary function that
-//    performs the recursion. The function should expect
-//    arguments in the range of 1 to 1 Million.

-//(2)  Complete the collatz bound function below. It should
-//     calculuate how many steps are needed for each number 
-//     from 1 upto a bound and returns the maximum number of
-//     steps and the corresponding number that needs that many 
-//     steps. You should expect bounds in the range of 1
-//     upto 1 million. The first component of the pair is
-//     the maximum number of steps and the second is the 
-//     corresponding number.
