Group results by AIA channel and study type

[wafels]

It would be good to provide the fitting results grouped by AIA channel and study type. This would enable direct comparison of the results for each AIA channel as a function of nanoflare heating frequency. For example, we could have three overlapping histograms that show the power law indices obtained in the AIA 171 channel, where each histogram shows the results for a particular nanoflare heating frequency. Two types of histogram could be shown, one that shows the number of results found in each channel, and another that shows a probability distribution, i.e., the sum of each probability distribution is 1.

Further, we can also show the spatial distribution of the results. First, we can add the masks to show where we have multiple results (again, one AIA channel, three nanoflare-frequency results). The other way to do this is to color each of the masks, say red,blue and green, to try to convey information on which results occur where.
