Hello uBLAS Contributors:

                                     I have applied to GSoC 2013 and
pitched implementation of SVD factorization for uBLAS. In order to better
prepare myself and to get my hands dirty at uBLAS, I ended up implementing
QR Factorization employing Householder Reflections using uBLAS. This is
only the first draft and will be needing significant improvement, e.g.,
computation of QR decomposition of 100 * 100 matrix takes around 30
seconds. But I guess just to get familiar with code base, it was a good
exercise. Over the next week or two I will be trying to optimize the code.

                                     I will be absolutely grateful if
contributors can have a quick glance at the code, and point me to any
improvements they can suggest. Particularly in speeding up matrix
multiplication.

I used Visual Studio 2010 to compile the code. I will try to get the code
running on my Ubuntu machine in a couple of days hopefully.

Here the header file:
