ASSIGNMENT: Name resolving

Using the template for the 4th assignment, you should implement name resolving as the first part of the semantic analysis (but ignore name checking of structure and union components - this will be done during type checking next week).

You must upload your solution as a ZIP file named xxxxxxxx-seman.zip, where xxxxxxxx represents your student identification number. The contents of the uploaded ZIP file must follow the exact directory structure of the template. The ZIP file must contain the complete source distribution (including previous phases) but should exclude ANTLR and generated files.
