Sir,

This in in regard to the Inserters project.I have been through the
bcrsmatrix.hh file throughly and some other documentation too of the files
related to it. I tried to find some bugs on this topic on the bugtracker at
Dune Numerics regarding this file to check my understanding of the code.
Did find one about not able to access undefined indexes but the person
posting the bug has posted the .diff file too for the code he seems right.
I went through it and it seems right to me too. I wished to ask whether I
am on the right track regarding this project and what should I do next to
improve my skills.

P.S. Last time you asked me to mention my name in mail header. Is this
format fine???

Thanking you,
Tilak Raj Singh
