*[].ExistByRefSorted (gb)
Function ExistByRefSorted ( Value As  ) As Boolean
Return the position of the first occurrence of a specific object in a sorted array.
If 
Start is specified, then the search begins at the 
Start position. By default the entire array is searched.
If 
Value cannot be found, 
-1 is returned.
Contrary to 
Find, this function always compare objects by identity
(i.e. by using their memory address). The 
_compare special method is not used.
This method only works if the array is sorted.
But it is faster than the 
ExistByRef method as it uses a binary search algorithm.
