      Returns a promise that is fulfilled when all the given promises have been
      fulfilled, or rejected if any of them become rejected. The return promise
      is fulfilled with an array that gives all the values in the order they were
      passed in the `promises` array argument.

      Example:

      ```javascript
      var promise1 = RSVP.resolve(1);
      var promise2 = RSVP.resolve(2);
      var promise3 = RSVP.resolve(3);
      var promises = [ promise1, promise2, promise3 ];

        // The array here would be [ 1, 2, 3 ];
      });
      ```

      If any of the `promises` given to `RSVP.all` are rejected, the first promise
      that is rejected will be given as an argument to the returned promises's
      rejection handler. For example:

      Example:

      ```javascript
      var promise1 = RSVP.resolve(1);
      var promise2 = RSVP.reject(new Error("2"));
      var promise3 = RSVP.reject(new Error("3"));
      var promises = [ promise1, promise2, promise3 ];

      RSVP.all(promises).then(function(array){
        // Code here never runs because there are rejected promises!
      }, function(error) {
        // error.message === "2"
      });
      ```

      `RSVP.race` allows you to watch a series of promises and act as soon as the
      first promise given to the `promises` argument fulfills or rejects.

      Example:

      ```javascript
      var promise1 = new RSVP.Promise(function(resolve, reject){
        setTimeout(function(){
          resolve("promise 1");

        // result === "promise 2" because it was resolved before promise1
        // was resolved.
      });
      ```

      `RSVP.race` is deterministic in that only the state of the first completed
      promise matters. For example, even if other promises given to the `promises`
      array argument are resolved, but the first completed promise has become
      rejected before the other promises became fulfilled, the returned promise
      will become rejected:

      ```javascript
      var promise1 = new RSVP.Promise(function(resolve, reject){
        setTimeout(function(){
          resolve("promise 1");
        }, 200);
      });

      var promise2 = new RSVP.Promise(function(resolve, reject){
        setTimeout(function(){
          reject(new Error("promise 2"));
        }, 100);
      });

      RSVP.race([promise1, promise2]).then(function(result){
        // Code here never runs because there are rejected promises!
      }, function(reason){
        // reason.message === "promise2" because promise 2 became rejected before
        // promise 1 became fulfilled
      });
      ```

      @method race
      @param {Array} promises array of promises to observe
      @return {Promise} a promise that becomes fulfilled with the value the first
      completed promises is resolved with if the first completed promise was
