Detailed Description

Simple function object for putting commas in lists.

This avoids a load of repeated code when you have reason to output a lot of things with comma-separated lists.

Initialize the object with the actual length of the list you want to print.

Each time you call comma() you'll get a comma or an empty string with just enough commas to format the list correctly.
