* Create developer facing GQL schema (`erc20.graphql`) for ERC20 contracts
* GQL `queries` that return useful information
* Individual token data corresponding to the ERC20 ABI
* Aggregate data like running 1-day, 7-day & 30-day `transfer` counts and volumes
* GQL `mutation` to add a new ERC20 contract to watch
* Create a server (`erc20-info-server`) to expose the above GQL API
* Initally, the GQL resolvers will return mock data
* Create a basic `React` app (`erc20-dashboard`) that consumes the GQL API from `erc20-info-server`.
* Create a new watcher (`erc20-watcher-ts`) that is capable of watching multiple ERC20 tokens, capturing their events and state
* Update the `erc20-info-server` GQL resolver to return data by querying the lower-layer `erc20-watcher-ts` GQL API
* For GQL result data, at a minimum, log the request and list of CIDs/mhKeys required to generate that result.
* Note: This implies, for example, performing aggregation in code instead of at the SQL layer.
* Create an ERC20 watcher factory (`erc20-watcher-factory-ts`) that auto-detects ERC20 tokens created on-chain and calls `erc20-info-server` to request watching them.
