--[[
This module is intended to be invoked by the ListMaster module. Depending on the style
passed to the parent, will parse and display the list item as a table row, subsection, etc.

Possible values that could be used for a members table:
  name, role, member_since, role, status, etc
Possible values that could be used for a tasks table:
  title, notes, page, owner, created, due, completed, priority, remaining, etc
  
Values can be passed in that aren't displayed, allowing for more robust storage
of metadata for each item (ie, any arbitrary value can be passed in that aren't
intended to be displayed, but instead facilitate machine-trackable data).
