 /* OSM Binary file format
 
 This is the master schema file of the OSM binary file format. This
 file is designed to support limited random-access and future
 extendability.
 
 A binary OSM file consists of a sequence of FileBlocks (please see
 fileformat.proto). The first fileblock contains a serialized instance
 of HeaderBlock, followed by a sequence of PrimitiveBlock blocks that
 contain the primitives.
 
 Each primitiveblock is designed to be independently parsable. It
 contains a string table storing all strings in that block (keys and
 values in tags, roles in relations, usernames, etc.) as well as
 metadata containing the precision of coordinates or timestamps in that
 block.
 
 A primitiveblock contains a sequence of primitive groups, each
 containing primitives of the same type (nodes, densenodes, ways,
 relations). Coordinates are stored in signed 64-bit integers. Lat&lon
 are measured in units <granularity> nanodegrees. The default of
 granularity of 100 nanodegrees corresponds to about 1cm on the ground,
 and a full lat or lon fits into 32 bits.
 
 Converting an integer to a lattitude or longitude uses the formula:
 $OUT = IN * granularity / 10**9$. Many encoding schemes use delta
 coding when representing nodes and relations.
