Adding problem2 solutions

This change adds several solutions for problem2:

* Brute Force - Visits each term and checks if even
* Even Terms - Visits every 3rd term
* Parllel - Distributes even terms across cores

Using a couple of different Fibonacci sequence generators:

* Fib() - Traditional recursive sequence generator
* FibIterative() - Iterative (non-recursive) sequence generator
* FibBinet() - Closed-form sequence generator (currently only accurate for n < 77)
