Fixing issue #33
Change the biom backend from CSMat to SparseMat

The biom format uses CSMat as a default backend, E-vident sees  some
performance benefit from using SparseMat, hence a biom configuration
file was added to the project.

The installation instructions had a dead link, this was also corrected.
