add to docs "prerequisites" in terms of skills

[sreichl]

@burtonjake: It would be good to think about what people need to learn in order to use MrBiomics effectively. For example they would need to already know how snakemake works, the way the job graph is generated. And then whether there is any way we can make this easier/reduce the barriers to using MrBiomoics.

• succinctly at the top of every module repo README w/ a link to resources

Specify target audience and their required skill set.
