Area Lib

Create areas using /area create <id> <from> <to>

You can add aditional regions using
/area add_to <id> <from> <to>
Similarly you can remove a region by standing inside it and running
/area remove_from
You can change the color of the rendered area outline using
/area set_color <r> <g> <b>

To completely delete an area use /area delte <id>

Note that these areas don't do anything by themselves, but require additional mods that can implement specific functionality for them.
