* 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);
