Compares the specified object with this map for equality. Returns
<tt>true</tt> if the given object is also a map and the two maps
represent the same mappings. More formally, two maps <tt>m1</tt> and
<tt>m2</tt> represent the same mappings if
<tt>m1.entrySet().equals(m2.entrySet())</tt>. This ensures that the
<tt>equals</tt> method works properly across different implementations
of the <tt>Map</tt> interface.
@implSpec
This implementation first checks if the specified object is this map;
if so it returns <tt>true</tt>. Then, it checks if the specified
object is a map whose size is identical to the size of this map; if
not, it returns <tt>false</tt>. If so, it iterates over this map's
<tt>entrySet</tt> collection, and checks that the specified map
contains each mapping that this map contains. If the specified map
fails to contain such a mapping, <tt>false</tt> is returned. If the
iteration completes, <tt>true</tt> is returned.
