Example `styled_list.lua`

--[[--
This example shows how to use custom styling with the list class. It illustrates
both using one specific style for a column, and also how to specify styles
dynamically based on the item. For conciseness' sake there is no `on_selection`
handler specified.

For the purpose of this example the `F6' key will be set to show the
example buffer. Provided that TextUI is installed, you can copy this to
your .textadept/init.lua, and press `F6` to try it out.
