Fix JSON encoding mistake
Add schema creation script
Scripts to process data, CSV data

The first script, csv1, processes the Oct28 data, and was a test bed for
some ideas on how to massage the data. However, it's not complete for a
list of all of the members, so csv2 processes the TNL-Roster.. file,
which of course is missing the voice part information. And anyway, I'll
want to go back to the Oct28 file to get event sign-up information. So
this is just a 'stick it in the repo for now' type commit.
Clean up create database script

This looks good -- after inserting a person, an event and a
person_event, I was able to list all people who had attended a specific
event with

  select p_firstname, p_lastName
    from person
    join person_event on pe_p_id=p_id
    join event on pe_e_id=e_id
   where e_id=1;

This produced the correct result.
