Smart Password Generator
------------------------
Author: Team Aerrow
Course: 2025CSET100 - Computational Thinking and Programming

Description:
A Python-based password generator that creates strong, secure, and personalized passwords.
Users can specify preferences for uppercase, lowercase, numbers, and special symbols.
It also personalizes passwords using the user's name while maintaining randomness.
