First commit
Added html versions of the notebooks

In the html folder one can find the html version of the notebooks, complete
with produced figures. Without the database (which is 1.4Gb) there is no way
to reproduce the results currently in all ipython notebooks, hence the html
versions. The individual species notebooks have the code to download zipped
files which contain smaller datasets relative to particular species, but these
files are also quite large (~300Mb).
Small update to README
Merge branch 'master' of https://github.com/pmsppinto/TFnet

Just getting the .gitignore.
