  		 * `build` is a recursive function that manages creation/diffing/removal
  		 * of DOM elements based on comparison between `data` and `cached` the
  		 * diff algorithm can be summarized as this:
  		 *
  		 * 1 - compare `data` and `cached`
  		 * 2 - if they are different, copy `data` to `cached` and update the DOM
  		 *     based on what the difference is
  		 * 3 - recursively apply this algorithm for every array and for the
  		 *     children of every virtual element
  		 *
  		 * The `cached` data structure is essentially the same as the previous
  		 * redraw's `data` data structure, with a few additions:
  		 * - `cached` always has a property called `nodes`, which is a list of
  		 *    DOM elements that correspond to the data represented by the
  		 *    respective virtual element
  		 * - in order to support attaching `nodes` as a property of `cached`,
  		 *    `cached` is *always* a non-primitive object, i.e. if the data was
  		 *    a string, then cached is a String instance. If data was `null` or
  		 *    `undefined`, cached is `new String("")`
  		 * - `cached also has a `configContext` property, which is the state
  		 *    storage object exposed by config(element, isInitialized, context)
  		 * - when `cached` is an Object, it represents a virtual element; when
  		 *    it's an Array, it represents a list of elements; when it's a
  		 *    String, Number or Boolean, it represents a text node
  		 *
  		 * `parentElement` is a DOM element used for W3C DOM API calls
  		 * `parentTag` is only used for handling a corner case for textarea
  		 * values
  		 * `parentCache` is used to remove nodes in some multi-node cases
  		 * `parentIndex` and `index` are used to figure out the offset of nodes.
  		 * They're artifacts from before arrays started being flattened and are
  		 * likely refactorable
  		 * `data` and `cached` are, respectively, the new and old nodes being
  		 * diffed
  		 * `shouldReattach` is a flag indicating whether a parent node was
  		 * recreated (if so, and if this node is reused, then this node must
  		 * reattach itself to the new parent)
  		 * `editable` is a flag that indicates whether an ancestor is
  		 * contenteditable
  		 * `namespace` indicates the closest HTML namespace as it cascades down
  		 * from an ancestor
  		 * `configs` is a list of config functions to run after the topmost
  		 * `build` call finishes running
  		 *
  		 * there's logic that relies on the assumption that null and undefined
  		 * data are equivalent to empty strings
  		 * - this prevents lifecycle surprises from procedural helpers that mix
  		 *   implicit and explicit return statements (e.g.
  		 *   function foo() {if (cond) return m("div")}
  		 * - it simplifies diffing code
