Installation and running automation, documentation reorganisation (wiki and README)

[anuragparida]

• The most important issue is that of installing and running the required programs again and again for running the project-
  • A setup.sh file should be made and Cassandra should be installed automatically without any additional user task.
  • The "Usage" section on the README.md file has a list of commands to be run everytime the program is to be run. Commands like sudo service cassandra start, ./artemis, sudo ./gradlew and opening the web browser at 127.0.0.1 should be done automatically by a shell script file.
• The Java backend should be moved to React-native or some other modern technology because the app is docker-based.
• The wiki for the project is empty and should be made and updated. Content from the individual sections of the README.md file should be taken and each section should have a new dedicated wiki page.
