[Proposal] Find the the maximum absolute row sum of matrix

["Edward J. Yoon" <ed...@apache.org>]

At the present time, dense matrix/vector almost implemented except below list:

- Matrix.Norm
- DenseMatrix.multAdd(double alpha, Matrix B, Matrix C)

Matrix.Norm.One is that find the maximum absolute row sum of matrix.
Here's my mapreduce idea.

- A map task receives a row n as a key, and vector of each row as its value
 - emit (row, the sum of the absolute value of each entries)
- Reduce task select the maximum one

Does anyone can help me to implement this?
And, Any advices are welcome.
