Add a function to limit a list of objects to a specific character limit. E.g., a list of people, addresses, etc that go onto a single text box

[nonprofittechy]

Something like:

safe_displayed_items(list, character_length, function_to_use=comma_and_list, map=str) => List[Any]

so you could customize the way the list is displayed, but default to comma_and_list like DAList already does. And then you would assume each item is displayed with str() but in some cases they might want to print the items a different way, like with on_one_line().

To decide: is this best for it to return a list of items, or the text representation of the list? presumably, if it preserves the datatype of the list (e.g., a DAList) it should be fine to return the truncated list.
