- yamlStartDocument -> yamlStartDoc
- yamlEndDocument -> yamlEndDoc
- yTagMap -> yTagMapping
* Improved code formatting at some places
* Fixed code documentation at some places
* Added generic objects to TODO list
* Removed obsolete parsing tests, these are superseeded
by yaml-dev-kit test suite integration
* Added raises pragma to every proc in yaml.nim

* Serializer: Basic support for tuples.
* Serializer: Properly parse int and bool types when given as
string with explicit tag.
* Fixed a bug in the lexer where an error would be raised if
characters not allowed in tag shorthands are used in local tags
* Fixed processing of object tags for all kinds of root nodes in Parser
* Improved dumper to output a space after a local tag
* Renamed some enumeration types to conform better to the YAML spec
* Added secondaryPrefix to YamlTagLibrary
* Added possibility to control tag output style independently from
presentation style in serializer
* Created local tags for all types that are serialized and use them in
