Backend for Hodle.

It implements a cryptocurrency powered by multiple copies of a giant Excel spreadsheet.

This exposes a Metamask-compatible RPC endpoint containing 26 ERC-20 tokens, but doesn't actually implement a Blockchain or an Ethereum VM. Instead, requests are translated into reads and writes to Excel spreadsheets (one spreadsheet per token).

TODO

• actually do the transactions - currently it just always return a hardcoded balance
