Reformat. Fix. Clean. Add. ...

See yourself ...

Just kidding ...
- Reformatted the source files. (space, braces, == true, ...)
- Fixed some bugs. (result table appears only one time at the maximum).
- Changed some things in layout ... (padding, spacing)
- Organized imports. -> Only some minor warnings.
- Set all serial ids to 1.
- Deleted some error code and non-reachable code ?

Think I had to separate formatting and fixing into 2 commits ...
