description:
Fix in reading in auxiliary mesh data. Mesh functions specified
in the data section of a mesh XML file may now specify values for
only a subset of the entities (for example the entities on the
boundary).

compiler/linker flags.

description:
Add support for attaching arbitrarily named data to meshes
in preparation for integration with VMTK.

It is now possible to attach an arbitrary number of
MeshFunction<uint> to a mesh. Each data set is associated with a
user-specified string.

Example:

  MeshFunction<uint>* f = mesh.data().create("boundary indicators", 2);

  f[0] = 3
  f[1] = 3
  ...

  MeshFunction<uint>* g = mesh.data()["boundary indicators"];
