class VectorBuilder[E] extends NumericOps[VectorBuilder[E]] with Serializable
A VectorBuilder is basically an unsorted Sparse Vector. Two parallel arrays are maintained, one of indices, and another of values. The indices are not sorted. Moreover, <B> indices are not unique in the index array. Furthermore, apply(i) and update(i, v) are linear in the number of active values in the array.
+ and - are linear operations: they just append to the end. Component wise multiply, divide, and dot product are also linear, but require creating a HashVector copy. (TODO: maybe a SparseVector?)
In general, these should never be used, except for building, or for doing feature vector type things where you just need a sparse vector with a fast dot product with a "real" vector.
