// - parameter fetchRequest: the `NSFetchRequest` instance to use with the `NSFetchedResultsController`
// - parameter from: an optional `CSFrom` clause indicating the entity type. If not specified, the `fetchRequest` argument's `entity` property should already be set.
// - parameter sectionBy: a `CSSectionBy` clause indicating the keyPath for the attribute to use when sorting the list into sections.
// - parameter fetchClauses: a series of `FetchClause` instances for fetching the object list. Accepts `CSWhere`, `CSOrderBy`, and `CSTweak` clauses.
