  *         1.1 1998 January 7 - officially implements DataInput

  *         1.2 1998 January 9 - add LERandomAccessFile

  *         1.3 1998 August 27

  *         1.4 1998 November 10 - add new address and phone.

  *         1.5 1999 October 8 - use cmp.LEDataStream package name.

  *

  * Tests Little Endian LEDataInputStream and LEDataOutputStream

  * and demonstrates the use of its methods.

  *

  * Output should look like this:

  *

  * 44

  * -1

  * a

  * -249

  * -123456789012

  * -649

  * -749

  * true

  * 3.14

  * 4.14

  * echidna

  * kangaroo

  * dingo
