SignedMessageOracle
===================

Signed message oracle contract - Allows to set an outcome with a signed message
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

-  **Author**: Stefan George - stefan@gnosis.pm
-  **Constructor**: SignedMessageOracle(\ *bytes32*
   ``_descriptionHash``, *uint8* ``v``, *bytes32* ``r``, *bytes32*
   ``s``)
-  This contract does **not** have a fallback function.
