/**
 * The datatypes are used when defining a new model using `Model.init`, like this:
 * ```js
 * class MyModel extends MyModel {}
 * MyModel.init({ column: DataTypes.INTEGER }, { sequelize });
 * ```
 * When defining a model you can just as easily pass a string as type, but often using the types defined here is beneficial. For example, using `DataTypes.BLOB`, mean
 * that that column will be returned as an instance of `Buffer` when being fetched by sequelize.
 *
 * Some data types have special properties that can be accessed in order to change the data type.
 * For example, to get an unsigned integer with zerofill you can do `DataTypes.INTEGER.UNSIGNED.ZEROFILL`.
 * The order you access the properties in do not matter, so `DataTypes.INTEGER.ZEROFILL.UNSIGNED` is fine as well. The available properties are listed under each data type.
 *
 * To provide a length for the data type, you can invoke it like a function: `INTEGER(2)`
 *
 * Three of the values provided here (`NOW`, `UUIDV1` and `UUIDV4`) are special default values, that should not be used to define types. Instead they are used as shorthands for
 * defining default values. For example, to get a uuid field with a default value generated following v1 of the UUID standard:
 * ```js
 * class MyModel extends Model {}
 * MyModel.init({
 *   uuid: {
 *     type: DataTypes.UUID,
 *     defaultValue: DataTypes.UUIDV1,
 *     primaryKey: true
 *   }
 * }, { sequelize })
 * ```
 * There may be times when you want to generate your own UUID conforming to some other algorithm. This is accomplised
 * using the defaultValue property as well, but instead of specifying one of the supplied UUID types, you return a value
 * from a function.
 * ```js
 * class MyModel extends Model {}
 * MyModel.init({
 *   uuid: {
 *     type: DataTypes.UUID,
 *     defaultValue() {
 *       return generateMyId()
 *     },
 *     primaryKey: true
 *    }
 * }, { sequelize })
 * ```

 * A virtual value that is not stored in the DB. This could for example be useful if you want to provide a default value in your model that is returned to the user but not stored in the DB.
 *
 * You could also use it to validate a value before permuting and storing it. Checking password length before hashing it for example:
 * ```js
 * class User extends Model {}
 * User.init({
 *   password_hash: DataTypes.STRING,
 *   password: {
 *    type: DataTypes.VIRTUAL,
 *    set (val) {
 *      this.setDataValue('password', val); // Remember to set the data value, otherwise it won't be validated
 *      this.setDataValue('password_hash', this.salt + val);
 *    },
 *    validate: {
 *      isLongEnough (val) {
 *        if (val.length < 7) {
 *          throw new Error("Please choose a longer password")
 *        }
 *      }
 *    }
 *   }
 * }, { sequelize });
 * ```
 *
 * VIRTUAL also takes a return type and dependency fields as arguments
 * If a virtual attribute is present in `attributes` it will automatically pull in the extra fields as well.
 * Return type is mostly useful for setups that rely on types like GraphQL.
 * ```js
 * {
 *   active: {
 *   type: new DataTypes.VIRTUAL(DataTypes.BOOLEAN, ['createdAt']),
 *   get() {
 *     return this.get('createdAt') > Date.now() - (7 * 24 * 60 * 60 * 1000)
 *   }
 *   }
 * }
 * ```
 *
 * In the above code the password is stored plainly in the password field so it can be validated, but is never stored in the DB.
