Add the documentation for Parser. Write Javadoc-style comments for Parser's public methods and AST nodes.

• Array type
• Tests for arrays

Implement Parser class, which builds AST for the defined grammar.

For now, semantic analysis is not complete. We need to cover more semantic errors.

• Check modifiable primaries for ability to assign to them
• Routines with return type must have return statements
• In-record variables should either have initial value as either constant or not specified at all

Write a number of tests to cover more possible situations. Especially, need to focus on testing invalid cases since there are not that many tests about it.

• Write more tests for different AST nodes (for both parsing success and failure)
• Implement missing test for complete programs (14 remaining)

• Records type
• Tests for records

Make parser use position data and store it inside AST.

• Design a structure for storing positions inside different nodes
• Given the data from tokens, add positions to nodes
• Write a small test suite verifying that it works correctly

This was specified as a requirement in the language description document.

Use readInt as an example.

• readReal
• readBoolean
• tests

Improve performance of the parser.

• Check performance for failing tests
• Find potential points of performance improvement

More complex programs with I/O; ~10 more.

Improve existing code structure.
