$Description: Reads char files one line at a time without EOF EOL bug.$
$KeyWordsOff: $

This class iterates through the characters in a Reader object one line at at time. It might seem like this is the same as the function of java.io.BufferedReader, and in fact it is. But BufferedReader has a bug that causes it to drop the last line in a text file if that file contains only an EOL marker and nothing else. This class avoids this bug.
