- Introduce a very simple class ParseMode which will become a simple
value object which can be used to control the behavior when errors
and inconsistencies are encountered in the parse and EclipseState
construction phases.
- Added ParseMode instance as second argument to all parseXXX()
methods.
Parser::parseData is quite useful for unit tests to prevent them
spilling files to everything. Also, what was formerly
Parser::parseFile has been renamed to Parser::parseStream and slightly
modified to not be specific for std::ifstream.
