* @param {Function} [attributes.column.get] Provide a custom getter for this column. Use `this.getDataValue(String)` to manipulate the underlying values.
* @param {Function} [attributes.column.set] Provide a custom setter for this column. Use `this.setDataValue(String, Value)` to manipulate the underlying values.
* @param {Object} [attributes.validate] An object of validations to execute for this column every time the model is saved. Can be either the name of a validation provided by validator.js, a validation function provided by extending validator.js (see the `DAOValidator` property for more details), or a custom validation function. Custom validation functions are called with the value of the field, and can possibly take a second callback argument, to signal that they are asynchronous. If the validator is sync, it should throw in the case of a failed validation, it it is async, the callback should be called with the error text.
* @param {Object} [options] These options are merged with the default define options provided to the Sequelize constructor
* @param {Object} options These options are merged with the default define options provided to the Sequelize constructor
* @param {Object} options.sequelize Define the sequelize instance to attach to the new Model. Throw error if none is provided.
* @param {Object} [options.defaultScope={}] Define the default search scope to use for this model. Scopes have the same form as the options passed to find / findAll
* @param {Object} [options.scopes] More scopes, defined in the same way as defaultScope above. See `Model.scope` for more information about how scopes are defined, and what you can do with them
* @param {Boolean} [options.omitNull] Don't persist null values. This means that all columns with null values will not be saved
