Write a program which reads in a dynamic # of floats from the user,
but uses a class to store the internal data.

You should have a function for input, a function to compute the
average, a function to compute the minimum and a function to compute
the maximum, all as public member functions of the class.

Your class should have an appropriate constructor and destructor.


Never pass "myvector" objects to your functions.
Always pass either:  
       "myvector &" or
       "const myvector &",
whichever is most appropriate for your function.

Allow the user to repeat this computation as often as they wish.
