/**

|
* A class which wraps a 2D array of bytes. The default usage is signed. If you want to use it as a
|
|
* unsigned container, it's up to you to do byteValue {@literal &} 0xff at each location.
|
|
*
|
|
* JAVAPORT: The original code was a 2D array of ints, but since it only ever gets assigned
|
|
* -1, 0, and 1, I'm going to use less memory and go with bytes.
