* GArray
*
* The fileindex creates a FileIndexId object for each writer id, a
* Hashtable is kept to map the id to the FileIndexId
*
* The FileIndexId also keeps all the values in a sorted GArray.
*
* Finding a value for an id/format requires locating the correct GArray,
* then do a binary search to get the required value.
*
* Unlike gstmemindex: All formats are assumed to sort to the
* same order. All formats are assumed to be available from
* any entry.
