FutarchyOracle
==============

Futarchy oracle contract - Allows to create an oracle based on market behaviour
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

-  **Author**: Stefan George - stefan@gnosis.pm
-  **Constructor**: FutarchyOracle(\ *address* ``_creator``, *address*
   ``eventFactory``, *address* ``collateralToken``, *address*
   ``oracle``, *uint8* ``outcomeCount``, *int256* ``lowerBound``,
   *int256* ``upperBound``, *address* ``marketFactory``, *address*
   ``marketMaker``, *uint24* ``fee``, *uint256* ``_tradingPeriod``,
   *uint256* ``startDate``)
-  This contract does **not** have a fallback function.

FutarchyOracle Functions
------------------------

setOutcome()
~~~~~~~~~~~~

-  **State mutability**: ``nonpayable``
-  **Signature hash**: ``0537665d``

Allows to set the oracle outcome based on the market with largest long
position

close()
~~~~~~~

-  **State mutability**: ``nonpayable``
-  **Signature hash**: ``43d726d6``

Closes market for winning outcome and redeems winnings and sends all
collateral tokens to creator
