Yes, I like it! @sphamil does this sound good to you?

I also want to consistently refer to the heat/fluids driver as either the "heat", "heat_fluids", or "heatfluids" driver. It's not very consistent right now. For example:

• The element for specifying the driver is <driver_heatfluids> (see here)
• The value of <denisty_ic> is expected to be "heat", not "heatfluids" (see here). Likewise, the Initial enum has the value heat (see here)

I'd like to use "heat" everywhere (not "heatfluids" or "heat_fluids"). It's shorter and you won't have to remember whether to use an underscore or not, which I think is important in writing an input file. Is that okay?
