FIxed issue in last commit: supports controller were not correctly
filling the holes without data.
Fixed duplication in supports and successful supports controller using a
concer.
Successfull supports controller will fill the holes without data in the
same way that supports controller does.
Supports controller now fill the holes in the results: When there are no
supports collected for one interval it takes the accumulated value from the
previous one.
Data starts in the publication date.
