 ///////////// CB support routines ///////////////

 // matCB - matrix dimX and dimY CB controls (in some cases this set contains abcCBs as well because they are part of the matrix)
 // abcCB - matrix dim (ABC) CB controls
 // subCB - subtrack CB controls
 // What does work
 // 1) 4 state subCBs: checked/unchecked enabled/disabled (which is visible/hidden)
 // 2) 3 state matCBs for dimX and Y but not for Z (checked,unchecked,indeterminate (incomplete set of subCBs for this matCB))
 // 3) cart vars for viewDD, abcCBs and subCBs but matCBs set by the state of those 3
