 Create the following **functions**:
 
-- `add_ele`: which adds an element to the value in the `Node`.
+- `add_element`: which adds an element to the list in the `Node`.
 - `how_many_references`: which returns how many times the value is referenced in the code.
 - `rm_all_ref`: which accepts an `Rc<String>` and removes all elements from the vector that are equal to that value. This should only happen if the two `Rc`s point to the same allocation.
