Compares the specified object with this entry for equality.
Returns {@code true} if the given object is also a map entry and
the two entries represent the same mapping. More formally, two
entries {@code e1} and {@code e2} represent the same mapping
if<pre>
(e1.getKey()==null ?
e2.getKey()==null :
e1.getKey().equals(e2.getKey()))
&&
(e1.getValue()==null ?
e2.getValue()==null :
e1.getValue().equals(e2.getValue()))</pre>
This ensures that the {@code equals} method works properly across
different implementations of the {@code MapEntry} interface.
