Decoding results suppose a structure of results.

[robbisg]

The Decoding object hypothesize results in a dict with rois.
This should be moved to RoiWrapper and use Decoding only for simple decoding results.

We should take into account the RoiDecoding object or other objects that inherit from Decoding superclass.

RoiDecoding must have a self.analysis.save call to move the responsibility to wrapped class and it should save

TODO:

• Remove for in Decoding.save
• Move for in RoiDecoding.save
• Wrappers must record objects for each ROI
• We can pass to save also scores and save passed scores.
