In itslwg/SupaLarna: Package for the SuperLearner vs clincians study

This function generates confidence intervals around point estimate(s) or around difference of two point estimates.

1 2	generate.confidence.intervals.v2(study_sample, model_names, the_func, samples, diffci_or_ci, outcome_name, digits = 2, ...)

`study_sample`	The study sample list. No default.
`model_names`	Character vector. Names model names. No default.
`the_func`	Function that generates key statistic. For example, model.review.AUROCC that generates AUROCC of given model(s), or model.review.reclassification that generates reclassification elements of given model(s). No default.
`samples`	Samples prepared as the study_sample. List of study_sample lists. No default.
`diffci_or_ci`	String. Whether to return confidence interval on difference of model_or_pointestimates, or return confidence intervals on model_or_pointestimates separately or no confidence intervals. Must be one of c("diff", "ci", "none")
`outcome_name`	Name of outcome variable. No default.
`digits`	Integer. Number of decimals when rounded. Defaults to 2.
