Vectorizer not able to handle data views

[madsendennis]

The vectorizer fromBreezeVector is not able to handle data views such as Transpose. In Scala, all row vectors are represented as a view, e.g. Transpose[Vector[T]].

Either a check should be implemented to ensure that views are not passed in or we can automatically apply the filter (example solution by @Andreas-Forster ):

if ( breeze.data.size == dim ) {
  EuclideanVector.apply[D](breeze.data)
} else {
  EuclideanVector.apply[D](breeze.copy.data)
}

In the second line breeze.copy.data could be replaced by breeze.toArray.
