INSERT INTO {$this->getTable('nfrsuper_awesome_example')} (name, description, other) values ('Example 1', 'Example One Description', 'This first example is reall awesome.');
INSERT INTO {$this->getTable('nfrsuper_awesome_example')} (name, description, other) values ('Example 2', 'Example Two Description', 'This second example is reall awesome.');
