 * A fixed-length, random-access sequence of bytes that also provides random

 * `ByteData` may be used to pack and unpack data from external sources
 * (such as networks or files systems), and to process large quantities
 * of numerical data more efficiently than would be possible
 * with ordinary [List] implementations.
 * `ByteData` can save space, by eliminating the need for object headers,
 * and time, by eliminating the need for data copies.
 * Finally, `ByteData` may be used to intentionally reinterpret the bytes
 * representing one arithmetic type as another.
 * For example this code fragment determine what 32-bit signed integer
 * is represented by the bytes of a 32-bit floating point number:
 *
 *     var buffer = new Uint8List(8).buffer;
 *     var bdata = new ByteData.view(buffer);
 *     bdata.setFloat32(0, 3.04);
