This function creates native tokens for Ocean Primitives. It can be invoked anytime, but Ocean Primitives always invoke it upon creation first.

It is implemented by the `OceanERC1155.sol` which is inherited by the actual Ocean implementation `Ocean.sol`. In order to call it you should pass Ocean address to the interface like in the example below:

```solidity
address oceanAddress = 0xc32eb36f886f638fffd836df44c124074cfe3584;

IOceanToken(oceanAddress).registerNewTokens(0, 1);
```
