/**
* @class ThreeSixty
* **The ThreeSixty slider class**.
*
* This as jQuery plugin to create 360 degree product image slider.
* The plugin is full customizable with number of options provided. The plugin
* have the power to display images in any angle 360 degrees. This feature can be
* used successfully in many use cases e.g. on an e-commerce site to help customers
* look products in detail, from any angle they desire.
*
* **Features**
*
* - Smooth Animation
* - Plenty of option parameters for customization
* - Api interaction
* - Simple mouse interaction
* - Custom behavior tweaking
* - Support for touch devices
* - Easy to integrate
* - No flash
*
* Example code:
* var product1 = $('.product1').ThreeSixty({
* totalFrames: 72,
* endFrame: 72,
* currentFrame: 1,
* imgList: '.threesixty_images',
* progress: '.spinner',
* imagePath:'/assets/product1/',
* filePrefix: 'ipod-',
* ext: '.jpg',
* height: 265,
* width: 400,
* navigation: true
* });
* **Note:** There are loads other options that you can override to customize
* this plugin.

* @singleton
* @param {String} [el] jQuery selector string for the parent container
* @param {Object} [options] An optional config object
