======Prime Numbers======

A prime number is a number that is evenly divisible only by 1 and itself. Considered starting at 2 and going to (presumed) infinity, prime numbers have uses in computing, especially due to their (as of yet) undiscovered layout in the number spectrum. Is there a pattern? We have yet to definitively discover such.

Design and implement a program that will do the following:

  * prompt the user for a lower and upper bound, store each in a variable
  * determine the primality of each value (lower and upper inclusive)
  * display each value, and whether or not it is prime (no other divisors) or composite (factors exist)
