/**
 *  Description:    This snippet sets a global variable (SharedPreference) to indicate
 *                  if Neighboring cells info CAN be obtained or has been obtained
 *                  previously. If it has been and suddenly there are none, we can
 *                  raise a flag of CID being suspicious.
 *
 *                  The logic is:
 *
 *                      IF NC has never been seen on device:
 *                          - NC list is NOT supported on this AOS/HW, so we do nothing.
 *                      IF NC has been seen before,
 *                          - NC list IS supported on this AOS/HW, so we set:
 *                              nc_list_present : "true"
 *                      IF NC list has been seen before AND current CID doesn't provide
 *                      one, we raise an alarm or flag.
 *
 *
 *  Notes:      a)  Not sure where to place this test, but let's try it here..
 *              b)  In TinyDB, the getBoolean() returns "false" by default, if empty.
 *
 *              c)   This will be called on every cell change (ref:  issue #346)
 *              d)  *** https://github.com/CellularPrivacy/Android-IMSI-Catcher-Detector/issues/383
 *
 *  Issue:
 *          [ ] We need a timer or "something" to reverse a positive detection once
 *              we're out and away from the fake BTS cell.
 *          [ ] We need to add this to EventLog
 *          [ ] We need to add detection tickers etc...
 *          [x] We need to use a global and persistent variable and not a system property
