The errors Contract
The errors contract is one of the core contracts on each IOTA Smart Contracts
chain.
The errors contract keeps a map of error codes to error message templates.
This allows contracts to store lengthy error strings only once and then reuse them by just providing the error code (and
optional extra values) when producing an error, thus saving storage and gas.
