 * Design and implement an application that randomly reads  100 numbers from 1 to 100, and then creates a chart
 * showing how often the values appeared.  The chart should look like one shown here (see pg 383, my book).
 * It shows how many values fell in the range 1 to 10, 11 to 20, and so on.  Print one asterisk for each value entered.
