- update to 5.2.2:
* Leader object is correctly initialized when the force_utf8
option is being used
* fix for the behavior of Field.indicators to preserve backwards
compatibility when setting the indicators to a list or tuple
of two items
* Added MARCMakerReader class for reading MARC data from a
textual representation of a MARC record, expanding the previous
capability of pymarc to output MARC records in this format
* The Leader class is now automatically initialized for easier
access and updates
* Created Indicators type to limit indicator length and improve
handling
* Improved documentation of record status
* Field objects now throw a KeyError exception if you try to
set a subfield since they don't contain subfields
* Fixed issue with iterating over fields and subfields
