Ref documentation found at http://greensock.com/docs/#/HTML5/GSAP/TweenMax/staggerTo/ 

An array of target objects whose properties should be affected, or selector text that gets passed to TweenLite.selector (for selecting DOM elements). For example, if jQuery (or similar) is loaded and you pass ".myClass", it would act as though you passed in an array of DOM elements that had the "myClass" class applied. The same behavior applies if you pass a jQuery object containing multiple elements (like $(".myClass")).

Update pickadate.d.ts typing for container option

Pickadate.js allows for the container option to be either a selector string
or DOM element. The latter is useful in many situations. See this line in the source:
