+ <li> New: Added support for curved interior boundaries, and general
+ manifold id description.
+ <br>
+ A new attribute was added to each triangulation object
+ (types::manifold_id) which allows one to specify a manifold
+ description, much in the same way we do for boundaries, also for
+ interior edges and faces. At the moment this information is used
+ only for objects of topological dimension less than spacedim, but a
+ generalization of the class Boundary<dim,spacedim> is on its way to
+ allow also curved cells.
+ <br>
+ For the moment, full backward compatibility is granted, and one can
+ keep using the old Boundary<dim,spacedim>, together with
+ Triangulation::set_boundary(), and Triangulation::get_boundary()
+ methods. However, this change suggests to use the types::boundary_id associated
+ with each boundary face to indicate only boundary condition types, and
+ it allows to separate the geometric meaning from the physical meaning. The
+ suggested usage is
+ - types::boundary_id is used for the physical meaning
+ - types::manifold_id is used for the geometric meaning.

<li> Changed: The functionparser library bundled with deal.II got replaced
by the muparser library.
