This method will take a selection of siblings and ensure they are the only chlidren in their first parent which can be placed anywhere (for example the first parent of a tableCell which can be placed anywhere is a table, and for a listItem is a list). The method ensures no redundant empty tags are created, so if the selection encompasses all siblings then no action is taken. Also in this commit are two test cases run against ve.dm.example.isolationData. Change-Id: I783bd5ecd9d43d61f9b2685985409b4d746cbe94
