TPKBundle	A zoom level consists of 1 or more bundles A bundle is physically always 128 columns by 128 rows but may be "logically" smaller (ie it doesn't necessarily have data for each row/column)
TPKFile
TPKFormat
TPKFormatFactorySpi
TPKReader
TPKTile	Tile object returned to the reader
TPKTile.TileInfo	Temporary utility object to keep tile location/length info Note that in a V1 cache only the tileDataOffset field is utilized as the length is stored at that location (32-bit int) and the actual tile data is at tileDataOffset+4 In a V2 cache both fields are used and populated directly from the tile's index entry
TPKTile.TPKTileSorter	Sort comparator -- sorts tiles by bundle and then the tile data offset
TPKZoomLevelV1	TPKZoomLevel interface implementation for ESRI Compact Cache V1 files TPK is a ZIP archive In V1 the bundle index is a separate file from the bundle data and index entries are each 5-bytes long.
TPKZoomLevelV2	TPKZoomLevel interface implementation for ESRI Compact Cache V2 files TPK is a ZIP archive In V2 the bundle index is a incorporated into the same file as the bundle data.
