Activity 34 (Cryptography)
Implement the cryptosystem in section Cryptography. Requirements:
- Flowchart 
- Has a command-line interface 
- Use modularization as much as possible, i.e., header files, functions for repetitive code. 
- What was your modularization approach to each part you have implemented, i.e., CLI, Caesar, Vigenère? 1-3 sentences per part are enough. Include this test in your README. 
- For your header files you use - includefolder.
- Your header file is documented using Doxygen syntax. 
Optional: Additionally implement Merkle-Hellmann Knapsack Cryptosystem.
