@Test
	public void tetRemoveLast() {
		assertEquals(20, (int) graphPath.getLast());
		assertEquals(20, (int) graphPath.removeLast());
		assertEquals(19, (int) graphPath.getLast());
	}
Test to verify if removeLast() function works correctly. At setUp() a GraphPath is created
containing 21 vertices, with the last vertex having integer 20. Assert checks if this is the
case. Second assert checks if 20 is again returned when removeLast() is called. Final assert
checks if now getLast() returns 19, to check if removeLast() actually worked.
