* #include an absolute path didn't work - because paths were taken to always be relative.

* WIP: First pass in supporting output of line error information.

* Add support for lexing to better be able to indicate SourceLocation information.

* Fix lexer usage in DiagnosticSink in C++ extractor.

* Update diagnostics tests to have line location info.

* Fixed test expected output that now have source location information in them.

* Better handling of tab.

* Fix test expected results for tabbing change.

* DiagnosticLexer -> DiagnosticSink::SourceLocationLexer
Added line continuation tests.

* Fix typo.

* Added String::appendRepeatedChar

* Change to rerun tests.
