Append class to all HashCodeBuilders in Gaffer for the below issue to minimise hash collisions.

@Test
    void name() {
        Foo foo = new Foo();
        Bar bar = new Bar();

        assertFalse(foo.equals(bar));
        assertNotEquals(foo.hashCode(), bar.hashCode()); //fails

        int a = 3;

        @Override
        public int hashCode() {
