/**
 * The opposite of `_.pick`; this method creates an object composed of the
 * own and inherited enumerable properties of `object` that are not omitted.
 *
 * @static
 * @memberOf _
 * @category Object
 * @param {Object} object The source object.
 * @param {Function|...(string|string[])} [predicate] The function invoked per
 *  iteration or property names to omit, specified as individual property
 *  names or arrays of property names.
 * @param {*} [thisArg] The `this` binding of `predicate`.
 * @returns {Object} Returns the new object.
 * @example
 *
 * var object = { 'user': 'fred', 'age': 40 };
 *
 * _.omit(object, 'age');
 * // => { 'user': 'fred' }
 *
 * _.omit(object, _.isNumber);
 * // => { 'user': 'fred' }
