+   * @name xos.uiComponents.Comparator
+   * @description
+   * This factory define a function that replace the native angular.filter comparator.
+   *
+   * It is done to allow the comparation between (0|1) values with booleans.
+   * >Note that this factory return a single function, not an object.
+   *
+   * The tipical usage of this factory is inside an `ng-repeat`
+   * @example
