Suggestion: adding a simple test with small sized data

[junaruga]

Dear Ernest,

You merged my pull-request to run tests in Travis CI. Thank you.

How do you think about adding a very simple test for bam2hits and mmseq commands with very small sized data and less dependency bio tools?

I can see the tutorial to test it here.
https://github.com/eturro/mmseq#estimating-expression-levels

And what I would like to know is how to test with very small sized data, if possible, not using or less using other dependent bio tools like bowtie, kallisto, trim_galore or samtools commands.

It's like trim_galore's case here. https://github.com/FelixKrueger/TrimGalore/blob/master/.travis.yml#L23-L26 . You see that trim_galore command is tested with very small sized data in .travis.yml (Travis CI).

Because I would like to see it for this repository. And I started to manage mmseq RPM in Fedora project recently. And I like to add a simple test to verify the mmseq command in the process to create RPM file regularly.

Thank you.
