Bumped up to version 1.6.0 for next version
Skeleton of VectorComparisonGlyphFilter

Compiles and loads as a plugin, but doesn't do anything.
Implemented FillInputPortInformation
Added two inputs
Made inputs 0 and 1 be required
Implemented RequestUpdateExtent
Added generation of simple output

It just copies the points from the first input. This is just to get
something working.
Bumped up to ParaView version 3.98.1

This fixes a build error in the ParaView VRPlugin. Unfortunately, it
introduces a new error on Mac OS X where the include for libusb isn't
available by default, nor is it necessary. I submitted a patch to
ParaView to fix this.
Added member variables ScaleFactor and DiskResolution

Added appropriate handling if no vector field is set in the input data
sets.
Exposed ScaleFactor and DiskResolution properties in GUI
Added partial disk geometry generation
Moved class instantiation outside loops
Implemented the magnitude difference glyph
Fixed wrong icon showing up in application window

It was showing the ParaView icon. I changed it to the MADAI Workbench
icon.
Fixed capitalization of Qt resource file name
Limited the number of tries to start the VRPN server

This seems to fix a mysterious error on Mac OS where bash can no
longer run commands. Limiting the number of tries at starting the
server seems like a reasonable thing to do in any case.
The client gives up after 10 seconds if no callbacks are invoked
Fixed segmentation fault when deleting vrpn_Analog_Remote

Fixed by moving the delete to vtkVRPNClient::Stop() instead of in
~vtkVRPNClient(). Not sure why that fixes it, but it seems to.
Put my stand-alone splat program into the repository.  Byt default, it
will not be compiled with the workbench, but since it is such a small
amount of code, there is no reason not to include it.
Renamed 'splat' directory to 'applications'

This should make it more obvious what is in that directory.
