This commit moves the internal enzo reader to a
separate header. The reason for doing this is
primarily to allow the re-use of the internal enzo
reader for the corresponding particles reader.

This commit moves the internal flash reader to a
separate header. The reason for doing this is
primarily to allow the re-use of the internal
reader for the corresponding particles reader.

Fixed warnings regarding empty loop body in
while statement in the internal EnzoReader and
a warning regarding comparisson between signed
and unsigned integer expressions.

This commit applies changes that enable
the use of the global controller
by default. Before, a NULL controller
indicated that the reader is parallel.
However, with this change, the Controller
is almost guaranteed to be non-NULL. To
determine whether the reader is running
serially or parallel, an additional helper
method was added which checks both if the
Controller is NULL and the total number of
processes associated with the controller.
Consequently, all conditional statements of
"if( this->Controller != NULL )" have been
updated to "if( this->IsParallel() )" which
implements the correct behavior.

Added missing VTK_AMR_EXPORT which was
causing link problems in the Client/Server
Python wrapper.

This commit introduces the following changes:
(1) Inherit from vtkObject instead of vtkPointSet.
This avoids the issue of inheriting some pure
virtual methods that do not really make sense in
the context of this class.

(2) Added some missing forward declarations and
headers.

Initial commit for particle support.

This commit introduces the following in the
AMR kit:

( 1 ) vtkAMRParticles:  A concrete instance of
      vtkPointSet that is designed for storing
      and accesing particle information

( 2 ) vtkAMRParticleType: An enum definition that
      allows for an extensible definition of the
      different particle types.

Fixed cut-plane initialization s.t. where the
center was not calculated correctly for a plane
with a Z-Normal.

Uncommented code that initialized and declared
porigin.

Replaced vtkAssertUtils calls with standard C library
assert functions since vtkAssertUtils is not a standard
VTK class.

Replaced code that was internally extruding
ghost layers in favor of the vtkAMRGhostCellExtruder
which encapsulates that functionality and makes
the ghost exchange code shorter and cleaner.

Added the ability to query & set the NumberOfGhostLayers.

A filter that implements functionality for extruding
a user-supplied of ghost cell layers given a serial
or distributed AMR dataset.

Updates to reflect the class name change
vtkAMRDataTransferFilter->vtkAMRGhostExchange

Rename class to vtkAMRGhostExchange which is a
more descriptive name for the behavior of this
class.

Remove headers for connectivity filter and data
transfer filter which were initially ther from
a copy-paste.

Implement functionality to populate the cell data
by direct injection.

Added functionality to initialize the cut-plane offset
s.t. that it is in the center of the computational domain.

Added assert() after extracting slice to ensure
that the planar topology is correctly calculated.

Added an assertion after extracting a slice
to ensure that the calculated dimension of
the slice uniform grid is 2.

Fixed issue wherein the global origin of
the AMR dataset was not computed correctly.

Fix minor typo resulting in miscomputation of
the slice origin when extracting the XZ plane.

Added functionality for extracting slice data.

Adding AMR slice filter to the repository

Added support for selectively loading data arrays.

Adding vtkAMRFlashReader which implements
the vtkAMRBaseReader interface.

Added functionality to initialize the array
selections s.t. when the file is first loaded
none of the field data arrays is selected.

Addded LoadAttribute & BlockAttribute to the
vtkInternalEnzoReader.

Fix issue in the vtkEnzoReadedInternal
wherein access to an object that was
not allocated was attempted. Now, the code
checks if the object is NULL before attempting
to access its attributes.

Fix issue wherein the looping of AMR blocks in
RequestData to loop through all the blocks that
are currently loaded instead of all the loops.

Updated AMR reader infrastructure, currently
consisting of the Enzo and Flash readers.
Still some ironing of the API is required...

Resolve some linking issues related
to undefined reference to vtable.

Initial implementation of the Enzo reader that
implements that vtkAMRBaseReader interface.

Adding base AMR reader class which encapsulates
common functionality, i.e, UI components and
Point/Cell data array selection that all concrete
AMR readers can inherit.

Initial implementation of a sweep algorithm
for AMR homogenization.

Modularized and improved the implementation and added
TestAMRProbe example to the repository.

Adding the vtkAMRProbeFilter to the repository,
a concrete instance of vtkMultiBlockDataSetAlgorithm,
that given a set of points and an AMR dataset instance
finds & extracts the blocks that contain the given
points.

Fixed issue wherein a dual node was orphaned when
a donor cell has been previously found from another
block.
