* Each nodelist has corresponding index file. Index file name is the
* same as nodelist, but extension is changed to the ".bni", so index
* file to the nodelist "net5020.ndl" will be called "net5020.bni"
*
* Nodelist index header:
*
* Offset Size Description
* -------------------------------
* 0x0000 4 bytes Nodelist file date
* 0x0004 4 bytes Nodelist file size
* 0x0008 4 bytes Total number of entries in index file
* 0x000c 4 bytes Unused
*
* Nodelist index is an array of next entries:
*
* Offset Size Description
* -------------------------------
* 0x0010 2 bytes Zone number
* 0x0012 2 bytes Net number
* 0x0014 2 bytes Node number
* 0x0016 2 bytes Point number
* 0x0018 2 bytes HUB number (I hope HUB is in the same zone:net)
* 0x001a 4 bytes Offset of string in nodelist file
