@jhp-lanl @dholladay00 @chadmeyer this is ready for review. I think there's more one can do in this space, but IMO this is a nice start. In particular, energy and pressure near normal density are significantly better resolved with this method.

In anticipation of enabling spiner tables to load data from another eos, I move the Bounds object out of sesame2spiner into singularity-eos/base, and add tests to it.

I also found and fixed the issue @pdmullen found in riot regarding extrapolation. It was a bizarre interaction between fast logs and eospac in sesame2spiner. Now fixed.

Thanks, @jhp-lanl !

I think the existing tests cover this, but please ensure that the tabular EOS changes are properly covered by our existing tests.

Yep already on that. The existing tests do cover this on re-git. So it's very important those get run before final merge.

[Yurlungur]

@dholladay00 please review. @chadmeyer please re-review or click approve depending.

[Yurlungur]

(tests now all passing on re-git.)

[dholladay00]

What are the implications if this condition isn't met, would it make sense to error?

[Yurlungur]

If the condition isn't met, it will just not adjust the number of points or the max. The table will still be valid, but there won't be a grid point exactly at the anchor point. I'd like sesame2spiner to basically always run... so I'd rather this not error out. But I'll add a warning.

[Yurlungur]

Thanks @dholladay00 I think I've addressed all your comments. Can you click approve if you agree? (I will not merge until post-change tests all pass on re-git)

[chadmeyer]

I think it looks good now for pushing. Good Job @Yurlungur!

[Yurlungur]

Thanks @chadmeyer @jhp-lanl @dholladay00 for your reviews! I now plan to merge as soon as the latest commit passes tests on re-git. Speak now if you have objections. :)

[jhp-lanl]

@Yurlungur since the Bounds class depends on spiner, can you wrap all of this in a SINGULARITY_USE_SPINER #ifdef?

I'm failing to build the tests when SINGULARITY_USE_SPINER is off.

I'll create an issue too.
