Automatically activate a conda environment when entering folders/project.
conda_auto_activate automatically activates a conda environment when
enterring a folder that contains a .condaauto file. The first line in the
.condaauto file is the name of the conda environment.
To make this work you have to source conda_auto_activate.sh from your
~/.bashrc.
source ~/path_to/conda_auto_activate.sh
conda_auto_activate is inspired by virtualenv-auto-activate.sh.
