modular interfaces that allow comparing algorithms

[satra]

create an interface to allow comparing functions, interfaces, workflows, by harmonizing and mapping the input

...as well as outputs. One of the inputs would be the name of the algorithm ("SPM, "FSL" etc.). Something like this has been implemented in BIPS (see https://github.com/INCF/BrainImagingPipelines/blob/28448086d661e729d56a97f19f949a3623da9b05/bips/workflows/gablab/wips/scripts/modular_nodes.py)

Similar ideas has been discussed in context of BIDSTransformers by @lodurality

Something like this #882 ?
