Clean up example code (old code had unbalanced quotes and parens).

Subroutine added to optionally wrap values into arrays. Checks to see if the value is already an array and if so returns it untouched.

Updates for execute_into_hash() which now allows you to process a query which could return the same key multiple times and can support parameters being passed into the statement prepare() method.

sub check_for_stops can be given a 3rd parameter, an object with the sub _save_log, to save the logs to. This is optional, ommitting it renders the sub functionally equivalent to the previous version

Incorrect passing of the DBConnection object to the execute update closure which meant we attempted to call out to attributes which did not exist on that object.

Cannot use the begin_work() command if we have turned off AutoCommit manually. We were doing the same thing

Making sure if AutoCommit was off we issue a rollback to signal the start of a fresh block. This seems to be easier than using DBI's begin_work() since that will error if we have already begun a transaction

for specifying inheritance.
