Re-Encode a String (Hex, Base64, URL, etc)

Demonstrates how to convert from one encoding to another. For example: base64 to hex, URL to base64, base64 to quoted-printable, etc.

Note: The ReEncode method is unreleased at the time of this writing (08-April-2008) The next major Chilkat Crypt2 release after this date will include the ReEncode method.
