This module provides an implementation of the HeaderRegistry API.
The implementation is designed to flexibly follow RFC5322 rules.
Eventually HeaderRegistry will be a public API, but it isn't yet,
and will probably change some before that happens.

An address can have a 'display_name', a 'username', and a 'domain'. In
addition to specifying the username and domain separately, they may be
specified together by using the addr_spec keyword *instead of* the
username and domain keywords. If an addr_spec string is specified it
must be properly quoted according to RFC 5322 rules; an error will be
raised if it is not.
An Address object has display_name, username, domain, and addr_spec
attributes, all of which are read-only. The addr_spec and the string
value of the object are both quoted according to RFC5322 rules, but
without any Content Transfer Encoding.

An address group consists of a display_name followed by colon and an
list of addresses (see Address) terminated by a semi-colon. The Group
is created by specifying a display_name and a possibly empty list of
Address objects. A Group can also be used to represent a single
address that is not in a group, which is convenient when manipulating
lists that are a combination of Groups and individual Addresses. In
this case the display_name should be set to None. In particular, the
string representation of a Group whose display_name is None is the same
as the Address object, if there is one and only one Address object in
the addresses list.

BaseHeadera| Base class for message headers.
Implements generic behavior and provides tools for subclasses.
A subclass must define a classmethod named 'parse' that takes an unfolded
value string and a dictionary as its arguments. The dictionary will
contain one key, 'defects', initialized to an empty list. After the call
the dictionary must contain two additional keys: parse_tree, set to the
parse tree obtained from parsing the header, and 'decoded', set to the
string value of the idealized representation of the data from the value.
(That is, encoded words are decoded, and values that have canonical
representations are so represented.)
The defects key is intended to collect parsing defects, which the message
parser will subsequently dispose of as appropriate. The parser should not,
insofar as practical, raise any errors. Defects should be added to the
list instead. The standard header parsers register defects for RFC
compliance issues, for obsolete RFC syntax, and for unrecoverable parsing
errors.
The parse method may add additional keys to the dictionary. In this case
the subclass must define an 'init' method, which will be passed the
dictionary as its keyword arguments. The method should use (usually by
setting them as the value of similarly named attributes) and remove all the
extra keys added by its parse method, and then use super to call its parent
class with the remaining arguments and keywords.
The subclass should also make sure that a 'max_count' attribute is defined
that is either None or 1. XXX: need to better define this API.

DateHeadera� Header whose value consists of a single timestamp.
Provides an additional attribute, datetime, which is either an aware
datetime using a timezone, or a naive datetime if the timezone
in the input string is -0000. Also accepts a datetime as input.
The 'value' attribute is the normalized form of the timestamp,
which means it is the output of format_datetime on the datetime.
