thanks Andrew for finding these

Changes from ARL's Repo (C Wrappers, DSM rework, Custom Types, Templates, GridControllers, TIFF integration, XdmfAggregate)

Elements of type Polyhedron (i.e. N face cells, where each face is a M edge
polygon) are in the following format:
[nCellFaces, nFace0Pts, id0_0, id0_1, ..., nFace1Pts, id1_0, id1_1, ..., ...]

Fix XdmfTopologyType vector to be reference rather than copy.

Added subset; modified Array's interaction with Function; added new functionality to XdmfInformation subarrays; adjusted documentation to make more uniform

made changes for preparations to push to master; still need to finish documentation changes and line length changes

Since the reference element for spectral elements is by definition different
than a standard element, make these have different types in Xdmf.

XdmfTopologyType.

Modify XdmfTopologyConverter and XdmfPartitioner to work with new
topology types.

Polyline requires nodes per element to be provided in order to allow
for non contiguous polyline structures. Modified polyline constructor to
accept nodes per element as a parameter. Modify I/O to read value correctly.

Using statements have been added to XdmfSharedPtr.hpp. All used of
boost::shared_ptr and boost::shared_dynamic_cast have been replaced
by shared_ptr and shared_dynamic_cast. Slight modification to XdmfCore.i
to get swig wrapping working again.

type is specified. Previously, for mixed topology types, this would return
0.0. This would result in unreadable xdmf files being written to disk.

For mixed topology types, the function now examines the connectivity table
and parses topology type ids to count the number of elements. An improved
comment was added to XdmfTopology to explain how mixed topologies are stored.
A test for mixed topologies was also added, dealing with a quadrilateral and
a polyline in 2D.

Added documentation to several methods. Modified Doxygen configuration file to
correctly process macros (tested using Doxygen 1.7.1). Correctly format
documentation to 80 characters per line.

Hopefully this will become a standard style for Xdmf development.
All spaces - 80 character line wrapping.

ENH: Cleanup comments and inheritance syntax a bit.  Remove unnecessary Geometry Types not needed since splitting structured and unstructured grids
into separate hierarchies.

ENH: Get equality functions working again, but keep it in the SWIG file rather the polluting the C++.

Added testing for this for both languages as well. In Java
since you are not allowed to overwrite operators, we just
ignore the warning and overwrite .equals. In Python, we
overwrite the operator.

ENH: Add XdmfGridRegular for CoRectilinear (Regular) Structured Grids.  Add test for interaction and output.

The macros
XDMF_CHILDREN and XDMF_CHILDREN_IMPLEMENTATION

add capabilities to add and remove children by index or property from a parent item.  This simplifies the code
as the same insert() getChild() calls were used throughout the code.

ENH: Add XdmfExodusReader for reading ExodusII files into Xdmf.  Add ability for XdmfArray::initialize() to take a size value to initialize the array to.

destructors to be publicly accessible.  Modify tests to work with new wrapping.

ENH: Modify ItemProperties to use shared pointers like the rest of Xdmf.  Modify swig wrapping to correctly
handle both non const and const shared pointers.

to write out the Xdmf graph.  Modify some random include statements for style.
