To Run locally (skip this section if you want to use devnet)

1. Run solana-test-validator

2. Download SPL locally https://github.com/solana-labs/solana-program-library/tree/762c584dfe88d857575d0e079a9022523670969b

3. cd /token-swap

4. cargo build-bpf

5. deploy /solana-program-library/target/deploy/spl_token_swap.so

   Note that spl_token_swap.so is not the default value the SPL offers to deploy, so you need to write the deploy path manually.

6. Change TOKEN_SWAP_PROGRAM_ID in the index.ts file to the local Token Swap program id

7. Change IS_LOCAL_DEVELOPMENT in the index.ts file to true.

8. Change "@solana/spl-token-swap": "0.1.2" to "@solana/spl-token-swap": "0.1.3" in the package.json

9. Comment out the nonce in the TokenSwap.createTokenSwap function. I's not needed since 0.1.3.
