Minor debug edits.
Debug XDMF/HDF5 output.

Some progress.
Merge branch 'master' into dev

Conflicts:
	src/Array4D.cpp
	src/XdmfIO.h
	test-xdmf/basicXdmfTest/basicXdmfTest.cpp
	test-xdmf/main.cpp
Fix merge.
Checkpoint commit for adding XDMF-reading capabilities.

Can open and read an XDMF file.  Number of scalar and vector quantities present is determined.  Data *NOT* inserted into UV structure.
Another checkpoint commit.

Compiles and almost works.  Looks as if there is some indexing issue when comparing original input to converted output.
Debug XDMF I/O routines.
Merge branch 'master' into dev
Merge remote-tracking branch 'remotes/origin/dev' into dev
Implement VTK read-in using library functions.

Compiles and appears to work with my single-scalar-quantity files.  Not tested on more-complex data files (multiple quantities, vectors, etc.).  Does not use the library functions for file-writing yet.
Debug VTK file IO using VTK libraries.
Update ignore settings.
Revert VTK-writing to use my routines.

Appears to be an error when using the VTK library to write data from my uniform volume class.  Using my own routine produces the expected results.  VTK libraries can read my file correctly.
Fix MSVC compilation errors.
Fix GCC compiler warnings & integration with QGenRecon.
Fix memory leak in VTK read-in.
