Block groups can be used to organize blocks of text within a document. They maintain an up-to-date list of the text blocks that belong to them, even when text blocks are being edited.
Each group has a parent document which is specified when the group is constructed.
The list of blocks in the group is returned by
blockList() . Note that the blocks in the list are not necessarily adjacent elements in the document; for example, the top-level items in a multi-level list will be separated by the items in lower levels of the list.
