New features

- Adds new keyword argument `ignore_missing` to `Overdo.do` method to
specify if method should raise `MissingRule` exception when there is
no matching rule for a key.
- Adds new CLI option `--strict` to the `do` command that sets the
`ignore_missing` argument to `False`. (51)
- MARC XML serialization from to_marc21.

Improved features
~~~~~~~~~~~~~~~~~

- Adds support for Python 3+.
- Uses an OrderedDict to let the external tools working on `dict`
(like json) behave correctly.
- All results from rules using `for_each_value` decorator are being
automatically extended. This is useful for repeatable MARC21 fields
with different indicators. (53)
- Record are stored in an immutable sorted structure which enables to
keep the intended order while offering easy ways to access, index
and manipulate.
- Adds two records to be tested.
- Reorders some of the assertion: `expected == actual`.

------------------------------------

New features
~~~~~~~~~~~~
