Proveably Random Raffle / Lottery

Description

Implementation of a proveably random smart contract lottery.

How it works

1. User enter by paying (a minimum) for a ticket
   • The ticket fees are going to the winner after drawn.
2. After X period of time, the lottery will automatically draw a winner.
   • This will be done programatically.
3. Uses Chainlink VRM and Chainlink Automation --
   • Chainlink VRF for randomness
   • Chainlink Automation for time-based trigger to draw winner

Tests!

1. Write some deploy scripts
2. Write our tests
   • work on a local chain
   • work on a forked testnet
   • work on a forked mainnet
