Add Caching to Travis CI #15

Closed aferritto closed 6 years ago

Currently Travis CI downloads Miniconda and builds the conda env from scratch every time. It would be better to:

Cache conda install script and miniconda install directory
Every time diff existing and new conda install shell scripts and completely rebuild if different
if only difference is in environment.yml call conda env update --prune
otherwise leave conda as is

This should save about 2 minutes per Travis run.
