Replace with std::stringstream implementation put for convenience
in XdmfStringUtils.hpp. Added a test as well.

Removes a boost call. Could be written in C++11, but not sure
of the rationale of removing the whitespace and it did not affect
tests.

Previous implementation of C interface passed raw pointers
up to user and it was unclear and inconsistent who owned the pointer
leading to bugs. The previous implementation lead to creation
of many copy constructors, many of which had bugs.

Now we pass opaque pointers to C which the user is *always* responsible for
freeing.

Remove broken copy constructors.

Update C tests so that all pass valgrind memory leak checks.

it breaks windows and some of Xdmf's own tests

these tests fail with it the other way.
C_CTestXdmfWriter (Failed)
C_CTestXdmfAggregate (Failed)
Cxx_TestXdmfAggregate (Failed)
Cxx_TestXdmfFunction (Failed) new fail
Cxx_TestXdmfSubset

xml file for aggregate is no different, but reading
balks at lack of "Content" the other way around

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

Some style. Some fixes, especially for windows with the exports and template changes.

More so adapt this to work well as a subdirectory in a larger project. Don't force settings
that the parent project owns, allow parent project to turn on tests without xdmf's tests and
make the name of the library an option so that parent can have two xdmfs.

Rework of HeavyDataController and HDF5Controller to remove extra code and move HeavyDataController away from being too dependent on hdf5 style
XdmfFunction now supports negative numbers in addition to the - operator
Reworked the interaction between array references and reading
Cleaned up some warnings that showed up in pedantic
Adjusted mpi tests to test against the MPIEXEC variable as opposed to hard calling mpirun
Still needs to be changed to work better with Cray mpi style execution
Updates to XdmfArrayType to allow for signed and floating point checking
General test and Documentation updates

Fully support parsing of nested xincludes in Xdmf files. Add a test to ensure
this remains supported - the test contains an xinclude to an element in a
separate file that itself is another xinclude to an XdmfInformation.

Add HDF5 tree writer test.

Fix reader to properly add content for DataStructure deprecated items.
Move whitespace trimming to reader where it is more convenient since
it can replace a check for the content being all whitespace.

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

changes for file splitting and functions along with assorted changes to XdmfFortran for possible speed increases

changes to file splitting, hyperslab not completely working yet. changes to Fortran to allow for polylines and releasing data after standard write

This reverts commit df13c70f.

Fix a bug in the reader that caused xincludes to not work properly when
nested. The xinclude needs to be evaluated in the local context rather
than the global context.

If xml is parsed from a string its document url could be NULL which causes
an error when building a map of document urls to documents.

Eliminate getRealPath calls which are expensive and not necessary in many cases
Parse XML node content only when necessary (parsing arrays)
Fix cases where copies were made of strings instead of using references
Use "map.insert()" rather than "map[] =" when adding properties to map

fragment was surrounded by an <Xdmf> tag.

Additional xmf files are now read in via href'd xincludes which broke
mapping of xmlNodePtrs to XdmfItems (which qas necessary to enable shared
pointer representation in file).  This mapping was fixed.

XdmfCoreReader.cpp had a bug that resulted in an infinite loop when
resolving xincludes. This bug was fixed. Added ability for xincludes
to resolve href links (links to other files).

Fixed formatting in XdmfWriter.cpp

Also add ability in XdmfReader to parse light data from a string rather than
just from disk.

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.

The code to deal with "Content" stored in XML Text Nodes was previously
rewritten to avoid use of xmlNodeGetContent() which recursively combines
all children node contents to the content of the current node, which was
undesired behavior. I was rewritten to find the first text node and return
the content of that node, but this was insufficient as sometimes the first
text node is whitespace. The code now finds the first text node containing
content, which works for all Xdmf and NetDMF files we have come across.
