/**

* Message console that sits below the editing area.

* <p />

* Be careful when debugging this class, because if it's throwing exceptions,

* don't take over System.err, and debug while watching just System.out

* or just call println() or whatever directly to systemOut or systemErr.

* <p />

* Also note that encodings will not work properly when run from Eclipse. This

* means that if you use non-ASCII characters in a println() or some such,

* the characters won't print properly in the Processing and/or Eclipse console.

* It seems that Eclipse's console-grabbing and that of Processing don't

* get along with one another. Use 'ant run' to work on encoding-related issues.
