+/**
+ * NestedFragmentContext
+ *
+ * This object captures the nested position of a fragment
+ * within a page. Given a target fragment and a page,
+ * the target fragment col/row within its parent is
+ * recorded, followed by the target fragment's parent
+ * col/row within its parent, etc.
+ *
+ * The purpose of this object is to support the
+ * create-new-page-on-edit feature. For example, when
+ * a fragment is moved, causing the creation of a new
+ * page, the information captured by this object
+ * allows the copy of the fragment in the new page to
+ * be located.
