// Search (inclusive) for the first index present that is equal to or greater than the passed index.
// (Start with index = 0 to find the first index in the array.) This is typically used to begin a sorted-order scan of the indexes present in a Judy1 array.

//   index - search index
//   returns uint64 - value of the first index that is equal to or greater than the passed index (only if bool return value is true)
//           bool   - true if the search was successful, false if an index was not found
