perf: calc - broadcasting of recalc after import - 20% of load time
As per:
Of a week of calc usage; it seems that we spend -far- longer fooling around with our dependency data structures, than actually calculating when after importing a sheet ;-)
@grandinj - not sure what this is doing, but surely notifying a bulk re-calculate-everything (if that is what we're doing - are we ?) should be short & sweet :-)
