Fixes
- Moved the three ConstraintBase functions into one, as it was giving trouble calculating everything - Gave each constraint the option to have a comment - SameTypeConstraint now can have multiple arguments - Redid the infinite loop detection - Implemented some more basic operators - Redid the division by zero for floats, it wasn't giving the right results. - Also postponed the updating the AST type3 until afterwards - Various linting fixes
