Hi Hilmi,
Thanks for suggestion about type of labeled vector. Basically, I agree that
your suggestion is reasonable. But, I would like to generialize `LabeledVector`
like following example:
```
case class LabeledVector[T <: Serializable](label: T, vector: Vector) extends
Serializable {
// some implementations for LabeledVector
}
```
How about this implementation? If there are any other opinions, please send a
email to mailing list.
