   Attempts to store the items in the $storehash, but only if they don't

   successfully created a new key value pair in the $namespace db.
   
   
   Args:
    $namespace: name of database to store values to
    $storehash: hashref to store to the db
    $udom: (optional) domain of user containing the db
    $uname: (optional) name of user caontaining the db
   
   Returns:
    'ok' -> succeeded in storing all keys of $storehash
    'key_exists: <key>' -> failed to anything out of $storehash, as at
                           least <key> already existed in the db (other
                           requested keys may also already exist)

     file: (optional) the file you want access info on
   
   Returns:
       a hash containing
           keys of 'control type' (possiblities?)
           values are XML contianing settings 
   
   Internal notes:
   
    access controls are stored in file_permissions.db as  array of arrays and a hash.
       array refs -> are locks
       hash refs -> all other types of controls
                    and will contain keys
   
                   'access' -> hash where keys are access controls and
                               values are settings (in XML)
   
                   'accesscount' -> scalar - equal to the next number to
                                    use as the first part of an access
                                    control key when defining a new
                                    control.
