"""A case-insensitive ``dict``-like object. 

Implements all methods and operations of 

``MutableMapping`` as well as dict's ``copy``. Also 

provides ``lower_items``. 

All keys are expected to be strings. The structure remembers the 

case of the last key to be set, and ``iter(instance)``, 

``keys()``, ``items()``, ``iterkeys()``, and ``iteritems()`` 

will contain case-sensitive keys. However, querying and contains 

testing is case insensitive:: 

cid = CaseInsensitiveDict() 

cid['Accept'] = 'application/json' 

cid['aCCEPT'] == 'application/json' # True 

list(cid) == ['Accept'] # True 

For example, ``headers['content-encoding']`` will return the 

value of a ``'Content-Encoding'`` response header, regardless 

of how the header name was originally stored. 

If the constructor, ``.update``, or equality comparison 

operations are given keys that have equal ``.lower()``s, the 

behavior is undefined.
