GM Coin

This deploys a smart contract on Solana to enable people to earn GM coin by just wishing "GM" on Solana blockchain. Smart contract enforces a cool off period so one has to wait before earning rewards.

Solana Instruction RPCs exposed

• init_associated_token : Used to create a de-facto associated token for the mint for a given public key.
• initialize: Initalize global variables for smart contract (e.g. cooloff_seconds).
• fund: Fund the vault from the original treasury/mint so it can be used to give GM tokens by the program.
• first_visit: Every GM user must make a "first visit". This initializes user-specific PDA to track user visits.
• visit_again: Every subsequent visit (1) records the visit count, (2) records the last timestamp of visit, (3) If cooloff_seconds have elapsed since last visit, reward user with 10 GM coins.
