A utility to create slideshows out of any sequence of HTML elements
It works by using javascript to transition each element smoothly (60fps) from display: none to display: block

To setup slideshow on your HTML, the following config needs to be set on the DOM elements

Assumptions:

Given a root element, the slideshow will include *all* siblings in slideshow until it encounters, data-slide-end='true'

HTML Config:

`data-ns-slide=true` - Indicates that the element is a participant in slideshow, note that
                     all of the elements with this attribute will have their display CSS property set to none;
                     It can cause some unintended side-effect, for example if used in conjunction with
                     `data-start-slide-show`
`data-auto-schedule=true`  - Signifies that the HTML element will appear on screen for some time and automatically
                          transition to next sibling.
`data-step-into=CSSSelector`  - Signifies that the element's children (that qualify the CSS Selector specified)
                               will be shown one at a time before moving on to next element. (Can be nested)
`data-slide-end=true`  - Signifies end of slideshow
`data-start-slide-show=true`  - This element will be considered the starting element of slideshow if no argument is passed to
                              QPSlideshow constructor.

Events:

Emits the following custom events to indicate status of the slideshow

`ns-slide-show-next` - When a transition from one slide to another is complete
`ns-slide-show-end` - When slideshow ends
