> The following code doesn't return true when testing equality of two SparseVectors, one
converted from a Breeze SparseVector.
> {code}
> val flinkVector = SparseVector.fromCOO(3, (1, 1.0), (2, 2.0))
> val breezeVector = linalg.SparseVector(3)(1 -> 1.0, 2 -> 2.0)
> flinkVector.equalsVector(breezeVector.fromBreeze)
> {code}
> The reason is that *fromBreeze* takes the number of non-zero elements *SparseVector.used*
as size when creating a SparseVector instead of the dimensionality *SparseVector.length*.
