-// This is an attempt at creating a uniform model for all NBT tags to allow for a uniform interface based on subclassing a single NBT tag super class.
-
-// NBT tags have a type (signed or unsigned?), optionally a name, optionally content type, optionally a size (signed), and content
-// Whether the type id byte is signed or not is unknown at this point. All other numbers are signed unless specified otherwise.
-// All tag types:
-// generic representation:  Tag(Byte:tag_type, String:name, byte[]:content, Byte:content_type, int32:size)
-// end:                     Tag( 0, "",          None,           0, 0) => used to determine the end of a compound tag, only the type gets stored
-// byte:                    Tag( 1, String:name, byte:content,   1, 1) => a single signed byte, size and content type not stored
-// int16:                   Tag( 2, String:name, int16:content,  2, 2) => big endian signed 16 bit integer, size and content type not stored
-// int32:                   Tag( 3, String:name, int32:content,  3, 4) => big endian signed 32 bit integer, size and content type not stored
-// int64:                   Tag( 4, String:name, int64:content,  4, 8) => big endian signed 64 bit integer, size and content type not stored
-// float32:                 Tag( 5, String:name, float32:content,5, 4) => big endian 32 bit floating point number, size and content type not stored
-// float64:                 Tag( 6, String:name, float64:content,6, 8) => big endian 64 bit floating point number, size and content type not stored
-// byte[]:                  Tag( 7, String:name, byte[]:content, 1, int32:size) => content stored prefixed with size, content type not stored
-// String:                  Tag( 8, String:name, byte[]:content, 8, uint16:size) => Java style modified UTF-8 string, size is unique bc it's 16 bit and unsigned, content stored prefixed with size, content type not stored
