There is a VIC Home directory, e.g.: "/home" ($HOME)
There is a VIC Room-base directory, e.g.: "/rooms" ($ROOM-BASE)
VIC Home and Room-Base is always an absolute path.

The new VIC is named "foo" by the user
The generated unique ID for this VIC is "123"

Thus the room dir is named "foo.123" ($ROOM)
This directory is created inside the $ROOM-BASE directory

The directory $ROOM-BASE/$ROOM is created
A default PK file is created in $ROOM-BASE/$ROOM/default.pk where:
    the PK 'AI Name' is "foo.123"
    the PK 'PK File' is $ROOM-BASE/$ROOM/default.pk
    the PK 'Current Directory' is $ROOM-BASE/$ROOM

    Thus the first 3 lines of this file would be:
    AI: foo.123 ; /rooms/foo.123/default.pk ; /rooms/foo.123
    PK: default.pk ; ; default.pk
    OI: default.oi ; ; default.oi
