The docs of MakeCcdVisitTableTask and MakeVisitTableTask don't make it clear how they and their output, ccdVisitTable and visitTable differs from ConsolidateVisitSummaryTask and its output (and the former's input), visitSummary. Per a slack thread, ccdVisitTable is a "survey-level" data product, aggregating visitSummary products; there are no visit/tract dataId keys. The docstring for MakeCcdVisitTableTask and its run method don't make this clear, and the structure of the ccdVisitTable isn't described there either. There is a ConsolidateVisitSummaryTask Task Topic page, but not one for MakeCcdVisitTableTask: in addition to expanding the docstrings, we need a task topic for it to put all the relevant information together.

Since this dataset appears to be specifically for the SDM ccdVisitTable, we should also link to the SDM schema docs, since those should describe the contents of this table. I don't know which of the various available schemas we should link to here, but the LSST baseline is probably the most relevant?

Most of the Tasks in postprocess.py should have Task Topic pages, too. We can get other tickets for those.
