solutions. Restore the NURBS meshes in the data directory to use their
original format.
Add a new FiniteElementSpace format for writing variable-order spaces,
currently implemented for NURBS spaces only. Move the reading of FE
space input in a new method: FiniteElementSpace::Load. Add new default
constructor for FiniteElementSpace that should be used with the Load
method.
Add a bunch of const qualifiers in NURBSExtension and NURBSPatchMap.
Extended the method Mesh::DegreeElevate to make it easier to work with
variable-order NURBS meshes.
In class Array, add copy constructors and copy assignment operators.
Add a number of FIXME comments.
