J. Fernando Sánchez	6a1069780b	Draft merge 51-improve parameters There are some unsolved issues, like representing the mix of analysis+parameters in a sensible way. I think we should somehow represent each of the analysis tasks with a unique ID, and it should contain the specific parameters used. Right now results.parameters is a mix of a dict with global parameters and a list with a dict of parameters per plugin.	2018-11-22 18:56:30 +01:00
