Write a recursive routine to generate GETINs with 4 or fewer calls
1) Start from squared set
2) do as in Seq Edit | Find C+P
3) create array, saving all possibilities, along with Private flag
4) Drill down to level 4
5) At each step, if formation is valid GETIN, check if already in
GETIN database. If not, add new record
6) Plenty of feedback, doevents, etc.
7) Initially, just start with level MS (before doing up thru C4D)
8) database driven, so I can pause it, and returm later.
9) DB REC: Unique Index, Level (1 to 4), CallName
10) Skip fuzzy matches.
