Relocate nexp.store #348
Description
For example, if the sequencer sends "expose 5" that invokes do_expose(5), stores 5 in the class, then at the end of the exposure, AstroCam::Interface::dothread_monitor_exposure_pending will decrement the class variable, --nexp and calls do_expose(nexp), I.E. do_expose(4). So it's a little redundant now that I look at it, because it's going to save 4 in the class when it already has it.
It could be made a little cleaner if this line were moved to the AstroCam::Interface::expose wrapper.
