## Function `create_object`

Create a new object by generating a random unique address based on transaction hash.
The unique address is computed sha3_256([transaction hash | auid counter | 0xFB]).
The created object is deletable as we can guarantee the same unique address can
never be regenerated with future txs.

## Function `create_object_from_account`

Use <code>create_object</code> instead.
Create a new object from a GUID generated by an account.
As the GUID creation internally increments a counter, two transactions that executes
<code>create_object_from_account</code> function for the same creator run sequentially.
Therefore, using <code>create_object</code> method for creating objects is preferrable as it
doesn't have the same bottlenecks.
