This looks like a bug in swig since the fix is not proper C++
Surrounded by a ifdef swig block. If anyone has a better fix for this
I'd like to use - this is a hack.

around to prevent compiler warnings.

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boost::shared_ptr and boost::shared_dynamic_cast have been replaced
by shared_ptr and shared_dynamic_cast.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.

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.

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: Change some method names in XdmfArray to be clearer and less verbose.  Modify files for documentation clarity.  Modify some minor things to prevent -Wall warnings in gcc.  Add python install rules and rpathing.

ENH: Commit Ken Renard's patches modifying populateItem and XdmfCoreReader to support some xpath functionality for backwards compatibility.

ENH: Rethink XdmfWriter / XdmfCoreWriter distinction and move XdmfSet to XdmfArray conversion in XdmfSet's traverse method.  If conversion is unneeded then do not traverse XdmfSet.

ENH: Make XdmfSet behave like a real std::set.  Modify some writing functionality to make this possible.

ENH: Add python wrapping for XdmfUtils and modify some swigisms to get reader working properly in python.

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.
