Returns 0x0000000000000000000000000000000000000000 as address where no pair exists.

# allPairs

function allPairs(uint) external view returns (address pair);

Returns the address of the nth pair (0-indexed) created through the Factory contract.

Returns 0x0000000000000000000000000000000000000000 where pair has not yet been created.

Begins at 0 for first created pair.

# allPairsLength

function allPairsLength() external view returns (uint);

Displays the current number of pairs created through the Factory contract as an integer.

# feeTo

function feeTo() external view returns (address);

The address to where non-LP-holder fees are sent.

# feeToSetter

function feeToSetter() external view returns (address);

The address with permission to set the feeTo address.

# Write functions

# createPair

function createPair(address tokenA, address tokenB) external returns (address pair);

tokenA and tokenB order is interchangeable.

Emits PairCreated (see Events).

# setFeeTo

Sets address for feeTo.

# setFeeToSetter
