Required methods

fn vesting_balance(
    who: &AccountId
) -> Option<<Self::Currency as Currency<AccountId>>::Balance>

    per_block: <Self::Currency as Currency<AccountId>>::Balance,
    starting_block: Self::Moment
) -> DispatchResult

Adds a vesting schedule to a given account.

If there already exists a vesting schedule for the given account, an Err is returned and nothing is updated.

Is a no-op if the amount to be vested is zero.

NOTE: This doesn't alter the free balance of the account.
