code: function append(root, isVirtual) {
        if (isVirtual)
          { makeVirtual.call(this, root); }
        else
          { root.appendChild(this.root); }
      }
docs: Append a new tag into the DOM
  @this Tag
  @param   { HTMLElement } root - dom node containing all the loop children
  @param   { Boolean } isVirtual - is it a virtual tag?
