  This assignment is practice in writing Java methods.  (Other programming
  languages use the words "function", "procedure", or "subroutine".)

  Three static class methods are created.  boxText() draws a box around a
  string of text using the characters "+", "-", and "|".  boxText() calls a
  second method named boxLine() to draw the horizontal lines.  boxText() is
  called by a third method named boxInfo() which formats a person's name and
  age into a message string.

  public static void main(String[] args)

    boxLine(0);                   // test boxLine() method
    boxLine(10);
    boxText("Hello. How are you?"); // test boxText() method
    boxText("12345678901234567890123456789012345678901234567890123456789012345678901234567");
    boxInfo("Mickey Mouse", 73);  // test boxInfo() method
    boxInfo("Tyrannosaurus rex", 65000000);
  }


/*
  boxInfo() method

  This method takes two parameters.  The first parameter is a string with a
  person's name.  The second parameter is an integer with that person's age.
  This method prints a message inside a box with information about the
  person.

  parameter.  The characters "+" and "-" are used to draw the line.
