* Represents a Gats string, that is, a string of 8-bit bytes. Unlike the
* standard Java string, a Gats string is a string of 8-bit bytes, not 16-bit
* UCS characters. If you want to transmit textual data, we highly recommend
* encoding it into UTF-8. You can do this by constructing a GatsString from
* a java string thusly: new GatsString( myStr.getBytes("UTF8") )
* <p>
* If you pass a java string into a GatsString instead of an array of bytes it
* will simply call the getBytes function. This may not be what you want in
* many cases, but will work great for simple cases.
