//// Description /////////////////////////////////////////////////////////////
// //
// plStatusLogs are our new encapsulated method of outputting text logs //
// for status (or other things, like, say, errors). They do more than just //
// output to the file, though; they maintain a scrolling buffer that //
// can be drawn on to the screen so you can actually view what's being //
// outputted to the log file (you can disable file writing if you wish). //
