* Enables the use of dynamic finders.
*
* Dynamic finders are just an easy way to do queries quickly without having to
* specify an options array with conditions in it.
*
* <code>
* SomeModel::findByFirstName('Tito');
* SomeModel::findByFirstNameAndLastName('Tito','the Grief');
* SomeModel::findByFirstNameOrLastName('Tito','the Grief');
* SomeModel::findAllByLastName('Smith');
* SomeModel::countByName('Bob')
* SomeModel::countByNameOrState('Bob','VA')
* SomeModel::countByNameAndState('Bob','VA')
* </code>
*
* You can also create the model if the find call returned no results:
*
* <code>
* Person::findOrCreateByName('Tito');
*
* # would be the equivalent of
* if (!Person::findByName('Tito'))
* Person::create(array('Tito'));
* </code>
*
* Some other examples of find_or_create_by:
*
* <code>
* Person::findOrCreateByNameAndId('Tito',1);
* Person::findOrCreateByNameAndId(array('name' => 'Tito', 'id' => 1));
* </code>
*
* @param string $method Name of method
* @param mixed $args Method args
* @return Model
* @throws {@link ActiveRecordException} if invalid query
* @see find
