I have a very large s/s that has a lot of recurring data in it. It is broken
into sections (not w/s) by date. I need to see only the first occurance of
each name in each section. For example, here is a sample:

1/1/2005
Time Reader Person
5:53:40 AM 0 Doe, John
5:56:35 AM 3 Smith, Mary
6:10:31 AM 0 Doe, John
6:14:19 AM 13 Doe, John
6:34:57 AM 13 Brown, Harry
6:37:31 AM 11 Smith, Mary

1/1/2005
5:49:48 AM 0 Smith, Mary
5:53:24 AM 3 Smith, Mary
5:56:44 AM 0 Brown, Harry
6:10:34 AM 13 Doe, John
6:11:01 AM 13 Brown, Harry
6:18:57 AM 11 Smith, Mary

What I want to see is this:

1/1/2005
Time Reader Person
5:53:40 AM 0 Doe, John
5:56:35 AM 3 Smith, Mary
6:34:57 AM 13 Brown, Harry

1/1/2005
5:49:48 AM 0 Smith, Mary
5:56:44 AM 0 Brown, Harry
6:10:34 AM 13 Doe, John
