Move trickle jquery.resize library and model functions into core

model functions:

getAllDescendantModels(parentFirst);
       /*
        * Fetchs the sub structure of an id as a flattened array
        *
        *   Such that the tree:
        *       { a1: { b1: [ c1, c2 ], b2: [ c3, c4 ] }, a2: { b3: [ c5, c6 ] } }
        *
        *   will become the array (parent first = false):
        *       [ c1, c2, b1, c3, c4, b2, a1, c5, c6, b3, a2 ]
        *
        *   or (parent first = true):
        *       [ a1, b1, c1, c2, b2, c3, c4, a2, b3, c5, c6 ]
        *
        * This is useful when sequential operations are performed on the page/article/block/component hierarchy.
        */

findRelativeModel(searchString, options);
       /*
        * Returns a relative structural item from the Adapt hierarchy
        *   
        *   Such that in the tree:
        *       { a1: { b1: [ c1, c2 ], b2: [ c3, c4 ] }, a2: { b3: [ c5, c6 ] } }
        *
        *       modelC1.findRelative("@block +1") = modelB2;
        *       modelC1.findRelative("@component +4") = modelC5;
        *
        *  options.limitParentId = limit to descendants only (should be renamed)
        *  options.filter = function(item, index) {  return true }
       *   options.loop = should wrap around
        */

jquery.resize library:
$('selector').on("resize", callback); is able to watch for changes in all document elements, not just the window

so long as you change getDescendents to getDescendants, I'm happy ;-)

I think it is. I just keep misspelling it. descendent != ascendant, descendant != ancestor.. come on brain.
