  11  * \class Branch
  12  *
  13  * A class describing a 'branch', i.e., a named alternative for
  14  * selectively outputting some parts of a document while suppressing
  15  * other parts.
  16  *
  17  * A branch has a name, can either be selected or not, and uses a
  18  * user-specifyable background colour. All these can be set and
  19  * queried.
  20  *
  21  * \class BranchList
  22  *
  23  * A class containing a vector of all defined branches within a
  24  * document. Has methods for selecting or deselecting branches by
  25  * name, for outputting a '|'-separated string of all elements or only
  26  * the selected ones, and for adding and removing elements.
