	Find an Array
	Implement a method that given two arrays as parameters will find the starting index where the second parameter occurs as a sub-array in the array given as the first parameter.
	Your implementations should return -1 if the sub-array cannot be found.
	Your implementation must implement the FindArray interface given bellow:
	public interface FindArray {
	int findArray(int[] array, int[] subArray);
	}
	Sample Input:
	[4,9,3,7,8] and [3,7] should return 2.
	[1,3,5] and [1] should return 0.
