Created new library code and new tests to compare distances between treatments in a given category.
Changed permissions.
Modified the documentation to be more complete.
Removed unnecessary imports.
Modified the library code with a few more changes to reflect the fact that chosen_samples is passed as a list, not a list of lists as I had thought. Updated the documentation some more and added compare_treatments.psp. This file is run after you have initiated the session (i.e. by running evident on one of the datasets) by opening a new window and pointing it to http://127.0.0.1/~will/evident/www/compare_treatments.psp?category=BODY_SITE&iterations=10 where you replace 'will' with your username and the category with whichever category in the mapping file you wish to use. Iterations is currently not linked to anything and whats being written out is just a dummy, but its a start.
Modified the .psp file to return averages over iterations excluding nans.
Modified the documentation from 1.6-dev to .9-dev.
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.
