add_item
adds descriptions you see when you look at something in the room.
add_item(mixed str,string desc)
add_item("twig","Yep, sure enough it's a twig");
you can also 
add_item(({"twig","branch"}),"Bits of a tree O.K.\n");
This will add multiple things with the same response.
Notes: Plurals. Don't need to, the MUD will take twig/twigs
    even branch/branches
