      Description

      In this refactoring, the performance is slightly increased by removing the overhead from breeze vector. The bottleneck is still in breeze norm which is implemented by activeIterator. This inefficiency of breeze norm will be addressed in next PR. At least, this PR makes the code more consistent in the codebase.
