Statistician and Email

The statistician page is pretty much complete.  The display itself could
use a fix-up; I'm terrible at asp.net.  The statistician csharp file
currently has a function that gets the average weight and/or age for a
particular trial group.  Those values are displayed on the page.

The "coin toss" for determining participant trial groups occurs in the
participant enroller csharp file.  I believe it's inside the update
participant function.

Added a function to the ParticipantDAO file that gets all participants
based on their trial.  Added trial group to database.  Changes are
reflected in the import.sql

Updated hotmail email file.  Aditya, check to make sure this works!
