Makefile, tests, includes, etc..

[brainstorm]

• Added Heng Li's strategy on the Makefile for bwa.
• Added further python tests, including one 1000 genomes dataset.
• New way to run tests: make tests

It would probably require going through this blog post since it'll run the tests via python:

But it would greatly simplify tests reproducibility, currently we're replicating efforts unnecessarily when it comes to testing.

If you need some help setting the python virtual environment, please, let me know!

I also removed the two .fq files since those are already covered in the testsuite itself, no need to replicate data. If you want to add custom .fq files you can use tests/data/custom folder for that. In any case, please, do not commit FastQ files if they can be downloaded/generated.
