// Index:
// In general, a single linear read of this file type is impossible.
// You have to read the index, often (but not necessarily) located at the end of the file.
// So, you can read the header, skip to the index, sort the entries, rewind and skip to
// each chunk, or you can seek from each index entry to the chunk, then return to the index.
//

//
//    case 4:  [8+(entry_count*28) must equal index_size]
//	  DWord index_null [zero]
//	  repeated once per entry_count:
//		DWord type

//		DWord Chunk_offset
//		DWord Disk_Size [or'd with 0x80000000]

//		Word unknown [1]

//	  DWord index_null [zero]
//	  repeated once per entry_count:

//		DWord Mem_size [decompressed size]

//	  DWord index_null [zero]
//	  repeated once per entry_count:
//		DWord group?

//	  DWord type
//	  DWord group?
//	  DWord index_null [zero]
//	  repeated once per entry_count:
//		DWord instance?
//		DWord Chunk_offset
//		DWord Disk_Size [or'd with 0x80000000]

//
// The overall structure appears that index type 4 has a unique type, group and instance
// for each entry, index types 5 and 6 all share the same type, and index type 7 all
// share the same type and group values. So 5, 6 and 7 are shorter per entry to save space
//
// Chunks:
//    Every chunk type is different. The index entry tells you where in the file the
//    chunk starts at, and how large it is. If it is compressed, the index gives the
//    uncompressed size. The compression is compatible with that used for DBPF V1, but
//    the compressed file header has changed from 9 bytes to 5. These 5 bytes are
//    counted as a part of the compressed size indicated in the index. The first two bytes
//    are the compression type 0x10, 0xFB or 0x50, 0xFB [0xFB10 or 0xFB50]. These appear
//    to decompress the same way. The next three bytes are the decompressed size, in
//    Big-Endian format (hi-byte to lo-byte). This should match the value found in the
//    index. Examples of decompression code are documented on the Sims2Wiki and at
//    moreawesomethanyou.com.
