"""Helper function that combines `KeyPair` and `Account` creation then calls to `create_new_account_tx` and `send_and_wait_tx`.
Creates an `Account` with new ``owner`` and ``active`` `KeyPair`, then
creates a `Transaction` that contains a list of `Actions` to create an account,
pledge tokens, buy RAM and transfer coins to the new account, and finally sends it.
Args:
new_name: The name of the account to create.
creator_name: The name of the account that will pledge tokens to the new account.
initial_ram: The amount of RAM to buy for the new account.
initial_gas_pledge: The amount of tokens to pledge for the new account.
initial_coins: The amount of coins to transfer to the new account.
algo_cls: The class type of the `Algorithm` to use to generate the `KeyPair`.
Returns:
A `Account` object.
Raises:
TransactionError: If Transaction.Status is unknown or if TxReceipt.StatusCode is not SUCCESS.
TimeoutError: If TxReceipt.StatusCode is TIMEOUT
or no transaction can be found after `wait_time` x `wait_max_retry` have passed.
