Develop a demo dapp that demonstrates basic userland zos usage

[theethernaut]

The dapp can be really simple, but it must achieve the following goals:

• At least one of the user contracts must be upgradeable.
• The user's contracts must interface with a kernel-land instance, such as a ERC721 proxy.
• The dapp must expose an intuitive deployment process and/or CLI tool usage.
• The dapp must be well documented, so that understanding how it works is very straight forward.
• The dapp must communicate with an injected zos version in development.
• (optional) The user can select which version of the kernel implementation to use.
