tried to make extract_text make a little more sense
modified submit_annotations text to make it a little easier to read / use
use root when recreating the schema
removed setup_db_permissions script -- that was for postgres
deleted another postgres file
removed all reference to oltp in scripts
removed more references to olap

since we're not using it at all
added a log to stderr if user runs itty server with default values, which will work but is probably wrong
