List of changes and additions:
* In class Mesh:
* Replaced the data fields BaseGeom, BaseBdrGeom, and BaseFaceGeom
with a new data field: mesh_geoms that is a bitwise mask for all
Geometry::Types found in the (local) Mesh including entities of
lower dimensions.
* The new data field mesh_geoms is set by the method SetMeshGen.
* Removed the (protected) method InitBaseGeom.
* Add new methods: HasGeometry, GetNumGeometries, and GetGeometries
that can be used to query the content of mesh_geoms. Also, added
class Mesh::GeometryList that can simplify such queries too.
* The methods GetFaceBaseGeometry, GetElementBaseGeometry, and
GetBdrElementBaseGeometry no longer have a default value for
their input parameter (the entity index) and accept only values
within their respective ranges.
* Removed the parameter of the method GetRefinementTransforms.
* Updated the methods PrepareNodeReorder and DoNodeReorder to
support mixed meshes.
* In parallel, the data field meshgen is now required to represent
information about the global mesh - updated relevant ParMesh
methods.
* Made any required changes outside of class Mesh due to the above
changes.
* Made various tweaks and improvements in the following methods:
CheckBdrElementOrientation, Mixed2DUniformRefinement,
Mixed3DUniformRefinement, UniformRefinement, and
GeneralRefinement.
* Updated the method PrintCharacteristics to print the types of
elements, boundary elements and faces used in the mesh.
* In the method ReadInlineMesh, replace remaining "pri" strings
with "wedge".
* In the mesh reader method ReadGmshMesh, recover the term "prism"
in the comments - it was replaced, unintentionally, I assume,
by "wedge".
* Add support for refinement of curvilinear mixed meshes:
* In class FiniteElementSpace, updated the methods:
GetLocalRefinementMatrices, GetLocalDerefinementMatrices,
RefinementMatrix, RefinementMatrix_main, as well as class
RefinementOperator to support mixed meshes.
* Add two new meshes: star-mixed-p2.mesh and fichera-mixed-p2.mesh
which represent examples of quadratic mixed meshes in 2D and 3D,
respectively.
* Add sample runs in ex1/ex1p using the new quadratic mixed meshes.
* In class Geometry:
* In the enumeration Type: removed the constant MIXED and added
new constant: NUM_GEOMETRIES.
* Add new static data field: DimStart[] that indexes the Types by
dimension: the Types of dimension 'd' are given by the range
[ DimStart[d], DimStart[d+1] ).
* In class ParNCMesh, added method GetGhostFaceGeometry that,
for now, returns Geometry::SQUARE.
* Update the return type of the method DofOrderForOrientation in
class FiniteElementCollection (and all derived classes) from
'int *' to 'const int *'.
* Removed the virtual method Element::GetRefinementFlag and made
the only relevant derived version (in class Tetrahedron),
non-virtual.
* In class Tetrahedron, added method Init.
* Added FIXME comments for some outstanding issues.
* In the mesh-explorer miniapp:
* Added option to enable or disable the 'refine' parameter when
reading a mesh from file.
* In the 'jitter' menu option, ask the user if the boundary
nodes should be moved or not.
* In the 'Print sub-element stats' menu option, count and print
bad/inverted elements by their Geometry::Type as well.
