 * PP 5.16 Develop a simple tool for calculating basic statistics for a segment
of text. The application should have a single window with
a scrolling text box (a JTextArea) and a stats box. The stats box
should be a panel with a titled border, containing labeled fields
that display the number of words in the text box and the average
word length, as well as any other statistics that you would like
