about to get rid of multinomial model, which is unlikely to be used and easy enough to do from scratch
added option for get_params in synthetic to generate dataset 2. noted that order for saving and plotting from draw_bird_locations method is C vs F. could allow control of order to change this discprancy. adding the *observes_from_file* method to poisson. one issue is how the self.days attribute is used in poisson model. seems its just used to keep track of number of days so far, so that methods that need that can be called without explicitly using number of days so far as an argument. so it doesnt seem that *observes_from_file* needs to update it until the end. we could get rid of it entirely for parallelism with onebird
