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

	func EqualSubArrays(list []int) [][]int

Given an list of integers A, return two sub-arrays with equal sums without changing the
order of the elements in the list.

For example given {1,7,3,5}, return {1,7} and {3,5} because 1+7 = 3+5 = 8.
