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

BUG: If we have compiled with Parallel IO and MPI, but are actually runnin a serial only process, the Parallel file access needs to be disabled.
Add a check in the XdmfHDF constructor to set UseSerialFile if either MPI is not initialized, or nprocs<=1

If HDF was compiled --threadsafe, DSM would Deadlock on MPIRecv().
Solution is to stay out of HDF5 Library on DSM Service.

  - Fix CheckFor64BitStreams to not re-check every time
  - Remove status messages from Xdmf2/*/CMakeLists.txt:
     "Finding Atomic Data Sizes"
     "Finding a 64 Bit Integer"
     "Checking for 64 Bit Streams"
    These messages are confusing since they appear every time.
    The CMakeOutput.txt and CMakeError.txt log files should have
    information about these checks when they are performed the
    first time anyway.

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.
