The Fascinating Fibonaccis!!

The Fibonacci Sequence is a famous string of numbers generated recursively in a feed-back type scenario: Each number in the sequence is generated by adding the previous two values. (Who thinks of these things!)

We just have to establish the first 2 numbers; Traditionally, they are '1' and '1'

Occassionally, you will see Fibonacci Numbers appear in a discussion about a population of rabbits multiplying: How many pairs of "wabbits" will there be after a year if it is assumed that every month each pair produces one new pair, which begins to bear young two months after its own birth?

It's interesting because Fibonacci Numbers occur in a variety of natural settings (daisy petal counts for example), and the ratio of two adjacent Fibonacci numbers, as those numbers get really large, is the mysterious 'Golden Ratio' which also appears in natural settings (like pi and e).

Let's calculate some Fibonacci Numbers!
