def get(self, key):

Returns the value for the specified key, or ``None`` if this map does not contain this key.

**Warning:
This method returns a clone of original value, modifying the returned value does not change the actual value in
the map. One should put modified value back to make changes visible to all nodes.**
    >>> value = map.get(key)
    >>> value.update_some_property()
    >>> map.put(key,value)

**Warning 2: This method uses __hash__ and __eq__ methods of binary form of the key, not the actual implementations
of __hash__ and __eq__ defined in key's class.**

:param key: (object), the specified key.
:return: (object), the value for the specified key.
