/*Write a program that reads a series of numbers (doubles) from the user,
then prints the mean and the range.
Notes:
• You do not know ahead of time how many numbers will be in the list.
• When you want to stop entering numbers, enter control+Z
• The range is the difference between the lowest and the highest number.
• The numbers will be in the range of 0.0 to 100.0. Ignore any numbers outside of this range.*/
