Given an arbitrary file "Values.txt", create a program that calculates the average of the prime values in the file.

Process:

1. Read Lines from "Values.txt"
2. Determine if the line is an integer
3. Determine if the integer is prime
4. Keep running average of primes
5. Print running average of primes (no formatting necessary)

Example 1:

Values.txt	Prime Values	Average
751 1090 971 1054 7 300 19 834 100 751 549 288 641 989 479 1388 1319 584	751 971 7 19 751 641 479 1319	617.2499999999999

Values.txt	Prime Values	Average
61 121 124 479 Blackberry 787 416 541 1011 Lemon 1051 493 827 140 Jackfruit 1103 Mango Blackberry 113 Blackberry 439 Orange Kiwi 1103 562 504	61 479 787 541 1051 827 1103 113 439 1103
