Returns a list of the items from the given index for the given size. If the index + size is out of bounds, the returned list will be shorter than the specified size, including only existing elements. If size if negative, an empty list is returned. If the given index is negative, the returned list will contain results as though it wasn't. Any 'negative' elements will be omitted, but the resulting size will match them as though they exists. e.g. The following test snippet would pass

 
 EList<String> list = Expressive.list("A","B","C");
 EList<String> items = list.getItems(-2,3);
 assertThat(items.size(), is(1));
 assertThat(items, is(list("A")));
