*
* \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.
