positive.code:  * A fixed-length, random-access sequence of bytes that also provides random
   * and unaligned access to the fixed-width integers and floating point
   * numbers represented by those bytes.
   * 
   * `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
  
negative.code:    * Returns the positive integer represented by the two bytes starting
     * at the specified [byteOffset] in this object, in unsigned binary
     * form.
     *
     * The return value will be between 0 and  2<sup>16</sup> - 1, inclusive.

     * Throws [RangeError] if [byteOffset] is negative, or
