Fix issue where new vector created for row when calling getRowView.
Faster nonZeroIndices which does not iterate over entire backing data array but only nonzero indices.
Add optimized case for set method when other vector is also sparse.
Merge branch 'develop' into sparse-speed
Added test for new ASparseIndexedVector#nonZeroIndices and fixed variable references after moving from SparseIndexedVector.
Removed temp file.
Reverted nonZeroIndices. The last change used ArrayLists and was relying on incorrect assumptions about relationship between index and backing data array.
Merge branch 'develop' of https://github.com/mikera/vectorz into develop
Fixed new column vector not being stored in ensureMutableColumn.
Added test for SparseColumnMatrix#setColumn.
Merge pull request #67 from mattrepl/develop
