- Renamed method start() to init() in Parser.
- Renamed method parseModule() to start() in Parser.
- Added method parseModuleDeclaration().
- Added class ImportParser which inherits from Parser. It's used as a lightweight parser for parsing module and import declarations.
- Added member isLightweight to Module.
- Removed calls to Parser.parseModule() and replaced them with Parser.start().
