[Users] Toward an Extensible Volume Integration Thorn

[Zach Etienne]

Hi all,

Back when I was at Illinois, I wrote a decent volume integration thorn,
which was nicely extensible, but required a very messy schedule.ccl to
perform all the ~40 integrations we used, with basically no options in
[].par files to modify or reduce the list of volume integrals (because it
would have made the schedule.ccl file *even* messier).

I am now trying to write a new version, which I would like to contribute,
open-sourced, to the ET. In this version, the schedule.ccl file is very
simple, and by simply specifying desired volume integrals in the [].par
file, the scheduling of these volume integrals is *supposed* to be done
automatically. Easier said than done.

Here's the output from the scheduling when the code is run:

        while (VolumeIntegrals::IntegralCounter)
          GROUP VolumeIntegralGroup: Evaluate all volume integrals
            GROUP VolumeIntegrandGroup: Evaluate all volume integrands
              VolumeIntegrals::ComputeIntegrand: [local] Compute Integrand
            GROUP VolumeIntegralSumGroup: Evaluate all volume integral sums
              VolumeIntegrals::DoSum: [global] Do Sum
            VolumeIntegrals::DecrementIntegralCounter: Decrement
IntegralCounter variable
        end while

Contrary to what is indicated above, the code in the loop actually
evaluates only the function in the [local] context, ignoring my [global]
requests, and giving a segfault (see full output from this loop below my
sig). Is there any way I can make this work, or am I doomed to repeat the
messy schedule.ccl of the past?
