Principles:

1. Functional LINQ approach without mutable state
2. Single class per day - for writing extension methods, a static class is required
3. No framework - each day is self-contained except for loading input
4. Neglect memory and performance - Unless it's fun to optimize

It's day 15 and the puzzles drained all my brain juice. I feel like a squeezed lemon ;) It's day 21 and I gave up writing clean code long time ago :/
