/*
* The table container helper is designed to simplify the task of
* writing a table handler for the net-snmp agent when the data being
* accessed is accessible via a netsnmp_container.
*
* Functionally, it is a specialized version of the more
* generic table helper but easies the burden of GETNEXT processing by
* retrieving the appropriate row for each index through
* function calls which should be supplied by the module that wishes
* help. The module the table_container helps should, afterwards,
* never be called for the case of "MODE_GETNEXT" and only for the GET
* and SET related modes instead.
