I have a CombineFn that has a large amount of state that needs to be loaded once before it can add_input or merge_combiners (for example, the CombineFn might load up a large lookup table used for combining).
Right now, to initialise this state, for each of the methods, I check if the state has already been initialised, and if not, I initialise it. It would be nice if CombineFn provided a SetUp() method that is called once to initialise this state (and a corresponding TearDown() method to clean up this state if necessary).
