Personal rewrite of the RedPocket contract
Key optimizations:
- Tokens are stored in one contract, rather than a contract being deployed for each user
- saves on gas costs
- easily see all laisees in one place
- Minting and depositing are now merged into one function
- one less transaction (and hence gas cost) for the user
- Withdraw function checks for token ownership rather than "contract" ownership (in previous design)
- balance is transferred with the token
- allow reuse of the same token for sending to multiple users (optional)
Optional changes:
- Change to ERC721Enumerable so that users can withdraw all laisees at once
- Two versions of withdraw functions
- One that allows for the user to withdraw all laisees at once
- One that allows for the user to withdraw a specific laisee
- Allow/disallow empty laisees
- Laisee is minted to sender first so that the recipient can see it is sent from which address
