Minor: Add foldLeft()

I had some doubts if this should be reduce...() or fold...(), and finally decided to do it the Scala way.

File:

-                      r3428599
+                      r3432928
+        }
+    }
+    /**
+     * @template A Accumulator type
+     * @template T Collection element type
+     *
+     * @param A $accumulator
+     * @param callable(A,T):A $callback
+     * @return A
+     */
+    public function foldLeft($accumulator, callable $callback) {
+        foreach ($this->array as $value) {
+            $accumulator = $callback($accumulator, $value);
+        }
+        return $accumulator;
+    }
+}
