- syntaxtree.py: reversed parameter order in transformer-functions: node is now always the first paramter again.

- parser.py: bug: pos values not initialized in nodes in history record, in case root parser did not match

split compileEBNF into two functions: compileEBNF and compile_parser; adjustments for compatibility with pypy3 / python 3.5

- added `start_parser` parameter to `GrammarBase.parse` in order to allow fine grained testing of ENBF syntax descriptions;
- added `dsl.suite_outdated`
- further corrections

- potential infinite loops are now caught when running parser and an error is reported; bug fixes, tests

- DSLsupport.run_compiler now produces callable DSL compiler script stubs; code reorganization all DHParser modules moved to a subdirectory containing the DHParser package; dhparser.py script remains in the main directory
