# Functions
# occurs(number, keep)
# - how often a die occurs in the given roll
# success(number, keep, add = 0, threshold = 0, compared = False)
# - how big the chance of succeeding a roll with a given threshold (difficulty)
# - with threshold, displays current roll as 0 and between -3 and +3 as results for a modified add value
# - without threshold, displays all possible outcomes
# crit(number, keep, add, threshold)
# - the rate of critical success for a given roll
# - without threshold, only critical failures are excluded
# avg(number, keep, add)
# - the average outcome for a given roll
# values used in functions:
# number - how many dice is rolled
# keep - how many dice to keep
# add - what modifier is added to the dice
# - default: 0
# threshold - what the target value is for the roll.
# - default: 0
# - disabled if 0
# compared - if compared is selected, lets you view with other compared rolls to form columns by threshold
# - default: False
# - compared must be used as a keyword, for example: success(4, 3, compared=True)
# - compared is designed to be used together with additional calls with compared=True
# - compared is not designed to work together with threshold. leave threshold at 0 if using compared mode
