Caesar Cipher – documentation

Each letter is moved shift places through the alphabet: new_position = (ALPHABET.index(letter) + shift) % 26. The modulo keeps positions in range for shifts past z. Decryption is encryption with -shift. Non-letters are left untouched and letter case is preserved.

API reference: run doxygen Doxyfile from the repository root and open docs/doxygen/html/index.html. The step-by-step plan is in plan.md.
