Add statement to problem 31
Add some tests to problem 31
Add iterative solution to problem31
Move test to the correct package.
Rename find to findIterative inside FindLongestConsecutiveSequence problem
Add a new test to problem31 and refactor algorithm to see green
Add tests to recursive implementation
Add tail recursive implementation to problem 31
Add two more tests to problem 31 to be sure our tail recursive and iterative algorithms support an edge case based on consecutive numbers with the same value
