*
* Description: This function will allocate the memory required for
* the visitor entry, and will find the appropriate
* visitor entry based on the index provided. If the
* search type is set to FIRST_ENTRY, we will return
* the first visitor entry in the Hash Table, otherwise
* the index is used.

* The visitor entry is then setup with the values found

* caller.

* Note, the caller is responsible for either freeing the
* memory, or calling free_faVisitorEntry()
*
* Returns: int, 0 if successful
