Problem: underline

  Write a static method called
   underline that takes a Scanner containing an input file as a parameter and
   that prints to System.out the same text with certain lines underlined.  The
   lines to be underlined all begin with a period.  The period should not be
   printed.  You should print the text that follows the period on a line by
   itself followed by a line of dashes equal in length to the text that follows
   the period.  For example, consider the following input:

        .Statement of Purpose
        I didn't expect to major in computer science until I took cse142.
        I liked it more than I expected and that got me hooked on cs.
        
        .High School Performance
        I got very good grades in high school, graduating in the top 10% of
        my class.
        
        .College Performance
        I have done well in my college classes, with an overall gpa of 3.5.

   If the text above is stored in a Scanner called input and we make this call:

        underline(input);

   the method should print the following output to System.out:

        Statement of Purpose
        --------------------
        I didn't expect to major in computer science until I took cse142.
        I liked it more than I expected and that got me hooked on cs.
        
        High School Performance
        -----------------------
        I got very good grades in high school, graduating in the top 10% of
        my class.
        
        College Performance
        -------------------
        I have done well in my college classes, with an overall gpa of 3.5.

   Notice that some of the input lines can be blank lines.
