=head2 deploy_schema

  DBICTest->deploy_schema( $schema );

This method does one of two things to the schema.  It can either call
the experimental $schema->deploy() if the DBICTEST_SQLT_DEPLOY environment
variable is set, otherwise the default is to read in the t/lib/sqlite.sql
file and execute the SQL within. Either way you end up with a fresh set
of tables for testing.

            $schema->storage->dbh_do(sub { $_[1]->do($chunk) }) or print "Error on SQL: $chunk\n";

  DBICTest->populate_schema( $schema );

After you deploy your schema you can use this method to populate
the tables with test data.
