[x] update name of doc file from methods.md to tutorial.md
[x] break commands over multiple lines, like in the Q2 docs
[x] add tutorial data to Snakemake folder, update instructions for accessing that data
~[ ] Note however that usually you would perform some manual filtering and trimming between these two steps, so these two commands likely won’t get you a publication quality phylogeny. : note that we are working on adding more support of these steps~ this is now part of #67
[x] Add suggestions on modifications that need to be made to Snakemake file to apply to non-tutorial data (e.g., update file names and N_THREADS)
methods.mdtotutorial.mdSnakemakefolder, update instructions for accessing that dataN_THREADS)
