Bootstrap 向导组件，对向导功能提供封装

基本用法

{{bu-wizard contentBinding="steps"}}

对应控制器

    Showcase.ShowComponentsWizardController = Ember.Controller.extend({
     init: function() {
       this._super();
       this.set('steps', Ember.A([
         Ember.Object.create({title: 'Foo', template: 'tabu/foo-tabpane'}),
         Ember.Object.create({title: 'Bar', template: 'tabu/bar-tabpane'}),
         Ember.Object.create({title: 'Baz', template: 'tabu/baz-tabpane'})
       ]));
     }
   });

禁用Step选择功能

有些时候，需要特定步骤的Wizard，则可以指定 disabled=true ，禁止Step选择，只允许通过代码改变Step

{{bu-wizard prevAllowed=false contentBinding="stepsNoPrev"}}

    Showcase.ShowComponentsWizardController = Ember.Controller.extend({
     init: function() {
       this._super();
       this.set('steps', Ember.A([
         Ember.Object.create({title: 'Step1', template: 'tabu/foo-tabpane', disabled="true"}),
         Ember.Object.create({title: 'Step2', template: 'tabu/bar-tabpane', disabled="true"}),
         Ember.Object.create({title: 'Step3', template: 'tabu/baz-tabpane', disabled="true"})
       ]));
     }
   });

通过编程方式，创建Wizard视图

{{bu-button title="Start Wizard" type="primary" clicked="createWizard"}}

    Showcase.ShowComponentsWizardController = Ember.Controller.extend({
     actions: {
       createWizard: function() {
         var body;
         body = Bootstrap.buWizardComponent.extend({
           content: [
             Ember.Object.create({title: 'Step1', template: 'wizard/step1', disabled: true}),
             Ember.Object.create({title: 'Step2', template: 'wizard/step2', disabled: true}),
             Ember.Object.create({title: 'Step3', template: 'wizard/step3', disabled: true})
           ],
           targetObject: this,
           onNext: "onNext",
           onPrev: "onPrev",
           onFinish: 'onFinish'
         });
         Bootstrap.ModalManager.open('manualModal', 'Wizard Title...', body, null, this);
       },
       onNext: function() {
         return console.log('NEXT');
       },
       onPrev: function() {
         return console.log('PREV');
       },
       onFinish: function() {
         Bootstrap.ModalManager.close('manualModal');
         return Bootstrap.NM.push('Wizard completed!');
       }
     }
   });
