 * Arbitrable interface.
 * When developing arbitrable contracts, we need to:
 * - Define the action taken when a ruling is received by the contract.
 * - Allow dispute creation. For this a function must call arbitrator.createDispute{value: _fee}(_choices,_extraData);
interface IArbitrable {
     * @dev To be raised when a ruling is given.
     * @param _arbitrator The arbitrator giving the ruling.
     * @param _disputeID ID of the dispute in the Arbitrator contract.
     * @param _ruling The ruling which was given.
    event Ruling(IArbitrator indexed _arbitrator, uint256 indexed _disputeID, uint256 _ruling);

     * @dev Give a ruling for a dispute. Must be called by the arbitrator.
     * The purpose of this function is to ensure that the address calling it has the right to rule on the contract.
     * @param _disputeID ID of the dispute in the Arbitrator contract.
     * @param _ruling Ruling given by the arbitrator. Note that 0 is reserved for "Not able/wanting to make a decision".
    function rule(uint256 _disputeID, uint256 _ruling) external;

rule is the function to be called by Arbitrator to enforce a ruling to a dispute.

Ruling is the event which has to be emitted whenever a final ruling is given. For example, inside rule function, where the ruling is final and gets enforced.
