Marionette牵线木偶，Backbone是脊骨的意思，Marionette是基于Backbone做扩展库，可以理解为把脊骨骨架绑线扯着变成牵线木偶动起来哈哈，使backbone更易使用呵呵！
构建或者扩展了很多新的东西，如：Application,Region,ItemView,CollectionView,CompositeView,LayoutView,AppRoute,Controller等等，把很多重复性的工作变成配置，程序入口引入了集中处理器Application，貌似Marionette的module不怎么好用，还不如用requireJS来得直观。
比较清晰，bower_components里面存放jQuery,underscore等等依赖js库及js框架，不用管它；css文件也不用理它。
