Optimized some algorithms

Refactoring of some algorithms, which should increase the performance of at least the ::Map method significantly. 

Labeled as Draft, because I didn't test the code apart from running the test cases. However, I believe the test cases don't cover these code sections, because the tests still pass, even if I manipulate the algorithms deliberately to fail.

See merge request smart-pattern/valentina!9
