10X output integration

In this update, we reworked the layout of the TAR-scRNA-seq repository so that it could contain multiple workflows- each snakemake workflow has its own sub-directory and is designed for different starting material. The first workflow was written to start from raw fastq files and has been put into the "from_fastqs" workflow. We have also added a new workflow that will run from already aligned files using the popular cellranger count workflow ("from_cellranger").
