@MechCoder Actually, it looks like the Python SparseVector constructor is
really inefficient, requiring either (a) a full pass over the indices or (b)
sorting the indices, depending on what is passed to the constructor. Would you
mind making a JIRA for making the Python constructor equivalent to the Scala
one? Thank you!
