* Normally, vesting balances are created automatically as part
* of cashback and worker operations. This operation allows
* vesting balances to be created manually as well.
*
* Manual creation of vesting balances can be used by a stakeholder
* to publicly demonstrate that they are committed to the chain.
* It can also be used as a building block to create transactions
* that function like public debt. Finally, it is useful for
* testing vesting balance functionality.
