6803ffd2 Properly implement the factory for the dax filters.
Add support for empty strinngs in SetInputArrayToProcess.

SetInputArrayToProcess ignored empty strings (treating them same as NULL
strings). This behavior makes it impossible to pick arrays that have no
names. Fixing SetInputArrayToProcess to not ignore empty strings. Also
added a check in GetInputArrayToProcess to handle the case where no
array association was specified.

Make it possible to override ClampPos.

This is needed to add support for editing control points where Y is not
clamped to [0,1].

change signatures for wrapping

Apparently functions whose signatures contain vtkSmartPointer
are not wrapped into python.  Change such methods of
vtkTreeHeatmapItem to contain ordinary pointers instead.

Revert "Pass std::strings through the OStreamWrapper."

This reverts commit c49b9c19d5f2a8124cb4884e93bd772285f405ac.

I'm going to remove this commit until we can figure out what to do
with strings. The conventions say std::string is our preferred string
container, but also that STL containers cannot be used in Common/Core.
