A utility to insert values into a list. You pass it an original list and it returns an altered list, and grows the list if required with padded values.
Works with numbers and texts. I typically use it for holding an ordered list of scores, or comments.

Another example use case is to hold prices per hour of the day. eg a lost of 24 hours, with prices each hour, need to be in order and need to hold duplicates.
