Fix code quality issues: remove unused variables and fix indentation

- Removed unused variable `projdir` (line 111)
- Removed unused commented-out variable `qadir` (line 324)
- Fixed inconsistent indentation to use 4-space multiples throughout lines 433-585
- All indentation now follows PEP 8 style guide
