/**
 * EDbFixtureManager represent the console command which helps you to manage your basic fixtures.
 * Available command properties:
 *    pathToFixtures - path to your fixtures file
 *    modelsFolder   - path to folder where your models classes lay, default to `application.models.*`
 *
 * Note:
 * 1) All attributes you want to fill via fixtures data, must be defined with `safe` validation rule (`rules()` method);
 * 2) Don't forget configure `tablePrefix` option for `db` connection definition;
 * 3) Your tables will be purged when you loading fixtures;
 *
 * For more complex info about usage, see README.md
