This enables to publisher to use the same smart contract for both constructor arguments `tokenRegistry` and `tokenLimiter`.
## Handling values
## Swapping tokens
The method used to execute token swaps is `withdraw(outToken, inToken, value)`.
The `value` argument refers to the value of `inToken` that will be transferred to the pool contract, in exchange for some value of `outToken` (see below).
In order to successfully execute the swap, an ERC20 "approval" must exist for the pool contract to spend at least the value of `inToken` specified by the `value` argument.
### Handling values
The pool contract does no checking whatsoever regarding the sanity of allowing tokens in the pool.
