* Use explicit tag when ref type renders to a scalar that can be
parsed to !!null
* Added test cases for this ref type fix
* renamed serialize to serializeObject and construct to constructObject
* added new serialize() and construct() procs that handle document
start & end
* re-raise AssertionError instead of swallowing it
* Some typo fixes in code
* nim documentation now generates API doc with source links
* presenter now uses "" if a string starts with @ or `
* Removed some outdated stuff
* Added raises pragma to every proc in yaml.nim
* Properly encapsulate exceptions from YamlStreams
* Discovered a Nim compiler bug and added a workaround
* Added possibility to query line, column and line content from
YamlParser
* Updated rst documentation
* Actually call callback in fastparse if available
* Fixed parsing YAML version
* fastparse now used for everything
* private/[lexer|parser].nim gone

* Catch reserved chars @ and `
* Fixed some test cases
* Made parser test cases use fastparse
* Made TagLibrary a ref object

* Always output "null" for yTagNull/yTypeNull scalars when
presenter is in JSON mode
* Added YamlWarningCallback that may be used to capture

* Removed yamlWarning as event kind
* Replaced checks for well-formedness in presenter with asserts
* Added checks for JSON compatibility of YamlStream in presenter
* Added proper type hints for special float values in
