ERC721 with Physical Asset Shipping Part 1

A Project that explores how to ship real, physical products, which are connected to ERC721 NFTs.

In this part we are using the OpenZeppelin ERC721PresetMinterPauserAutoId.

In the next part we are reducing it to a more low-level functionality and discuss gas costs and potential savings, as well as the shipping module.

In the final part we are building a small Web3 UI around this.
