The Collatz Conjecture, or 3x+1

This is a program to practice my rust skills and demonstrate an interesting maths problem called the Collatz Conjecture.

Explanation

The collatz conjecture is a maths problem with 3 simple rules:

• If the number is odd, multiply by 3 and add 1.
• If the number is even, divide by 2.
  
• Once the number reaches 1, stop, because 1 becomes 4, which becomes 2, which becomes 1.
