/**
 * Reconcile the children of a new VNode with the children of an old VNode by
 * traversing the two collections of children, identifying nodes that are
 * conserved or changed, calling out to `patch` to make any necessary
 * updates to the DOM, and rearranging DOM nodes as needed.
 *
 * The algorithm for reconciling children works by analyzing two 'windows' onto
 * the two arrays of children (`oldCh` and `newCh`). We keep track of the
 * 'windows' by storing start and end indices and references to the
 * corresponding array entries. Initially the two 'windows' are basically equal
 * to the entire array, but we progressively narrow the windows until there are
 * no children left to update by doing the following:
 *
 * 1. Skip any `null` entries at the beginning or end of the two arrays, so
 *    that if we have an initial array like the following we'll end up dealing
 *    only with a window bounded by the highlighted elements:
 *
 *    [null, null, VNode1 , ... , VNode2, null, null]
 *                 ^^^^^^         ^^^^^^
 *
 * 2. Check to see if the elements at the head and tail positions are equal
 *    across the windows. This will basically detect elements which haven't
 *    been added, removed, or changed position, i.e. if you had the following
 *    VNode elements (represented as HTML):
 *
 *    oldVNode: `<div><p><span>HEY</span></p></div>`
 *    newVNode: `<div><p><span>THERE</span></p></div>`
 *
 *    Then when comparing the children of the `<div>` tag we check the equality
 *    of the VNodes corresponding to the `<p>` tags and, since they are the
 *    same tag in the same position, we'd be able to avoid completely
 *    re-rendering the subtree under them with a new DOM element and would just
 *    call out to `patch` to handle reconciling their children and so on.
 *
 * 3. Check, for both windows, to see if the element at the beginning of the
 *    window corresponds to the element at the end of the other window. This is
 *    a heuristic which will let us identify _some_ situations in which
 *    elements have changed position, for instance it _should_ detect that the
 *    children nodes themselves have not changed but merely moved in the
 *    following example:
 *
 *    oldVNode: `<div><element-one /><element-two /></div>`
 *    newVNode: `<div><element-two /><element-one /></div>`
 *
 *    If we find cases like this then we also need to move the concrete DOM
 *    elements corresponding to the moved children to write the re-order to the
 *    DOM.
 *
 * 4. Finally, if VNodes have the `key` attribute set on them we check for any
 *    nodes in the old children which have the same key as the first element in
 *    our window on the new children. If we find such a node we handle calling
 *    out to `patch`, moving relevant DOM nodes, and so on, in accordance with
 *    what we find.
 *
 * Finally, once we've narrowed our 'windows' to the point that either of them
 * collapse (i.e. they have length 0) we then handle any remaining VNode
 * insertion or deletion that needs to happen to get a DOM state that correctly
 * reflects the new child VNodes. If, for instance, after our window on the old
 * children has collapsed we still have more nodes on the new children that
 * we haven't dealt with yet then we need to add them, or if the new children
 * collapse but we still have unhandled _old_ children then we need to make
 * sure the corresponding DOM nodes are removed.
 *
 * @param parentElm the node into which the parent VNode is rendered
 * @param oldCh the old children of the parent node
 * @param newVNode the new VNode which will replace the parent
 * @param newCh the new children of the parent node
