/*
The tokenfactory module allows any account to create a new token with
the name `factory/{creator address}/{subdenom}`.
- Mint and burn user denom to and form any account
- Create a transfer of their denom between any two accounts
- Change the admin. In the future, more admin capabilities may be added.
