I've added asserts in the ctor, @jhp-lanl @Yurlungur could you let me know what the physical bounds on those parameters so that appropriately bounding checks can be added to the ctor.

@dholladay00 where is this MR at? Should we merge it?

[dholladay00]

We could, I think I did this to reduce FPE's in SAP. Perhaps it's good to do in general. I'm not opposed to merging it.

[Yurlungur]

It's a pretty small changeset. I think we might as well.

[dholladay00]

we should probably create an issue to robusify all analytic EOS's in a similar fashion.
