Heather can't find instructions on how to change/update the database schemas,
so she's writing this to make it easier for others to change.

Suppose you add a new table or column or something to the database.  You will
need to do 3 things to properly set it up:


1. in dbconfig dir: add newtable.md, and add include(newtable.md) into ipp.m4
   If the table already exists, and you are just modifying it, you just need to
   edit the oldtable.md

2. figure out what changes are needed to get the gpc1/isp/uip/ssp up
   to the current schema.  Add those changes at the bottom of
   changes.txt, and modify gpc1/isp/uip/ssp.

3. edit ippTools/share/pxadmin_create_tables.sql.  This is the sql that creates
   an empty database.
