BUG:vtksys::ConvertToOutputPath was adding quotation marks around file paths that have spaces. This broke some tests for xdmf Iron in pv3. Still need to fix a couple more tests.

BUG: When merging changes prior to committing, I missed one origin setting fix. Removed a stray origin set to get parallel pieces appearing right

ENH: Add Time support to Reader. We check for CollectionType attribute on the main top level grid, and if it is temporal, we collect the list of time values from each sub grid. This is exported. When Time values are requested we output the correct sub grid.
Lots of internal changes to tidy up the code and handle information.
BUG: Several bug fixes for reading in parallel. Extents were not always correct. Seem to be ok for image data now

COMP: Trigger a rebuild of this file on morva (comment only change) -- it did not rebuild automatically (visual studio) after a new -D option was added to the CMakeLists.txt file.

redesign can be found at http://www.vtk.org/Wiki/VTK/Composite_Data_Redesign.

ENH: Change XDMF reader to produce full trees, multiblocks within multiblocks, when given a domain with nonuniformgrids inside nonuniformgrids, and to produce atomic data sets, vtkDataSets, when given a domain with a single uniformgrid.

BUG: More work on xdmf reader. Each enabled grid has to get its own information object. Now that this is fixed I am enabling the four remaining legacy tests. Not sure why image data multiblock colors the outlines with block id and others do not but I've changed the test to set it to solid color to make it pass.

BUG: Fix memory leak, delete Reader's DOM last, other things refer to the structs it owns, if it goes first their refs in destructors are invalid. STYLE: vtk indents and correct reader's description.

BUG: Fix what appears to be an error regarding switch from old code that used levels as the group id, to the new code which uses level to determine the dataset within the group. In any case this change lets you load the other sample data sets in paraviewdata without crashing.

ENH: Update paraview3 to use xdmfnew. Fix serial (non MPI) compilation, copy xdmfwriter from xdmf1, add removegrids() method to xdmfreader to synch grids and arrays when domain changes, and protect against two uses of an null pointer for undo/redo.

      progress notification when data object is requested (it leaves the GUI
      progress bar hanging when UpdatePropertyInformation is called).

      GUI Panel basically rewritten.  Uses a new XdmfHelper proxy to provide GUI
      interaction before first accept.  That is to update selections without
      breaking undo/redo.

number of groups is number of first level grids
datsets are the leafs of the trees.
