/// @title An interface for a contract that is capable of deploying Uniswap V3 Pools
/// @notice A contract that constructs a pool must implement this to pass arguments to the pool

/// @dev Called by the pool constructor to fetch the parameters of the pool
/// Returns factory The factory address
/// Returns token0 The first token of the pool by address sort order
/// Returns token1 The second token of the pool by address sort order
/// Returns fee The fee collected upon every swap in the pool, denominated in hundredths of a bip
