DHParser Version 0.8.0 (24.6.2018)
..................................

- refactoring of error reporting: it is now done centrally through the
  (newly introduced) syntaxtree.RootNode object; makes it faster and easier
- "step by step" guide added to the documentation
- XML is now a first class citizen for serialization next to S-expressions:
  xml serialization can now also be read with syntaxtree.parse_xml() plus
  better serialization with syntaxtree.Node.as_xml()
- added example: XML-Parser
- added optional CST-reporting on a case by case basis to the testing
  framework, using the "*"-marker to indicate which test should add CSTs to
  the report
- moved compilation support to a separate module: compile.py
- source mapping added if preprocessor changes source code
  (see module preprocess.py)
- new semantics for syntaxtree.Node.__str__: now includes error messages;
  use Node.content to retrieve the content without any error messages
- LaTeX-example: better AST-transformations.

- dhparser script now creates and initializes project dir
- parsing is now based on a StringView class which other
  than plain Python strings does not copy strings when
  slicing. (Speeds up parsing for longer documents.)
- AST-transformations now receive the complete context, i.e.
  the list of all parent nodes instead of just the node to
  transform
