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