A utility protocol for custom NSManagedObjects that makes querying contexts simpler and more convenient. Requires Swift 2.

	import CoreData

	protocol Fetchable
	{
	typealias FetchableType: NSManagedObject

	static func entityName() -> String
	static func objectsInContext(context: NSManagedObjectContext, predicate: NSPredicate?, sortedBy: String?, ascending: Bool) throws -> [FetchableType]
	static func singleObjectInContext(context: NSManagedObjectContext, predicate: NSPredicate?, sortedBy: String?, ascending: Bool) throws -> FetchableType?
	static func objectCountInContext(context: NSManagedObjectContext, predicate: NSPredicate?) -> Int
