Problem: The Repository didn't had any files for Containerisation. It takes too long to start the local server with too many steps.

Solution: With docker and compose files, now Anyone can start development server in only one command.

Tasks: Done all the tasks

• [x] Adding dockerfile for web ("/")
• [x] Adding dockerfile for server ("/server")
• [x] Adding Docker-compose file for Development server. ("Docker-Compose.Dev.Yaml")
• [x] Adding Docker-Compose file for Production server. ("Docker-Compose.Prod.Yaml")
• [x] Adding ".env.example" file if needed.
