When building data structures for use with interactive data manipuluation, it is often handy to have data structures that can be efficiently indexed by position (like a vector) as well as readably indexed by name (like a hash table). The NamedIndex type here maps unique names to integer indexes, looking up ByteString indexes in a Dict and passing other index types through. The NamedVector type implements a simple use case, with a backing vector of an arbitrary type.
