[vtkusers] multiblock time series file writing

[Gerrick Bivins]

Hi All,
After seeing a post this morning about "Seperation of <Points> and <Cells> datablock from UnstructuredGrid (.vtu) files<http://vtk.1045678.n5.nabble.com/Separation-of-lt-Points-gt-and-lt-Cells-gt-datablocks-from-Unstructured-Grid-vtu-files-td5720669.html>",
I thought it might be possible to use this to write out MultiBlock/Composite files temporally . Unfortunately, it looks like the settings
from the root CompositeDataWriter aren't passed to the data writers for the leaves. It also seems to ignore putting the
"TimeValues"  type information in the meta file (root xml file for the multiblock dataset).
For the leaves, the settings issue causes problems with the writing of those blocks:
1)Time information is not present
2) written files are invalid xml as the file begins with a broken offset tag something like:
   offset="6468764"0"?>

Issue 2  can be seen by simply attempting to write out an xml multiblock file.
I worked around it by setting the code writer to Binary mode explicitly.

Are these bugs or known limitations of multiblock format?
Gerrick
