[Paraview] Cosmo Reader - 64bit IDs

[David E DeMarle]

I will take a look at this tomorrow. I suspect it was hardcoded
initially but I should be able to make that configurable pretty
easily.

Because the data sets I have use a very large number of particles, they use a 64bit int for the ID tag, rather than the 32bit expected by the reader.   Looking at the source code for the reader (and HaloFinder) I see that there is an #ifdef ID_64, which if I understand correctly will compile the code using 64 bits for the particle IDs, just as I need.  So my first question is, is this understanding correct? If so, how do I configure ParaView to build with the ID_64 defined?  Is there some place that I need to add -DID_64 when running ccmake?  Also, I assume this means that it will then only read datasets with the 64bit IDs.  I do also have some data sets that use the standard 32bit ID format.  I was hoping there would be a way (via the GUI perhaps) to specify the precision of the IDs, and use the same e
