Simple-Bank

This is a bank service where we will provide API to fronted for doing things such as:

1. Create and manage bank accounts, which are composed of owner’s name, balance, and currency.
2. Record all balance changes to each of the account. So every time some money is added to or subtracted from the account, an account entry record will be created.
3. Perform a money transfer between 2 accounts. This should happen within a transaction, so that either both accounts’ balance are updated successfully or none of them are.
