List every data set the portfolio names

Record each data set as a component of its own — what kind of file it is, the control card member whose IDCAMS DEFINE creates it, the jobs that allocate it new, and how many jobs, steps and programs touch it — with who touches each file, a row per job and program, and the chain each file goes through in order, from the card that defines it through the job that creates it to the jobs that read it. FindDataSets answers the same question and marks the DD cards and DEFINE commands that make a file; this one produces the tables and changes nothing.
