+ * `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
