Suggestion: add bioconda installation instructions

[chollenbeck]

The conda package manager now supports dDocent installation. You could add this alternative installation method to the documentation somewhere:

Easy local install with bioconda

Install Miniconda: http://conda.pydata.org/miniconda.html

Add the bioconda channel:

conda config --add channels bioconda

Create a dDocent conda environment:

conda create -n ddocent_env ddocent=2.1

Activate the dDocent environment:

source activate ddocent_env

Run dDocent:

dDocent ...

Close the environment when you're done:

source deactivate

Now, that I updated the bioconda version, this will be perfect. Thanks.
