TestOddlyRepeatedNumber tests solution(s) with the following signature and problem description:

	func OddlyRepeatedNumber(list []int) int

Given a slice of integers that are all repeated an even number of times except one,
find the oddly repeated element.

For example given {1, 2, 2, 3, 3} return 1. Given {1, 2, 1, 2, 3} return 3.
