PKEuS 4f1f6e1824 Improved simplification of calculations:
- Use more generic patterns
- Look on operator precedence more consequently
-> Made a TODO test case from a test case that worked previously, because the calculation is simplified so that the problem isn't detected any more.
Changed comment "Coding style checks" to "Checks", because it didn't fit
