Substrate !ink NFT simple implementation

---

This is a simple working version of base NFT smart contract written using latest (as of this date) !ink 3.0.0-rc3.

To run all tests:

cargo +nightly test

To compile to WASM:

cargo +nightly contract build 

Original wasm size: 47.4K, Optimized: 26.3K

Once your contract is compiled you can find artifacts in: <PROJECT_DIR>/target/ink

• nft.contract (code + metadata)
• nft.wasm (the contract's code)
• metadata.json (the contract's metadata)

If you are facing any issues please follow the setup step of substrate environment at:
