SDIFF \_key1\_ \_key2\_ ... \_keyN\_
====================================

*Time complexity O(N) with N being the total number of elements of all the sets*
    Return the members of a set resulting from the difference between
    the firstset provided and all the successive sets. Example:

::

    key1 = x,a,b,c
    key2 = c
    key3 = a,d
    SDIFF key1,key2,key3 => x,b

    Non existing keys are considered like empty sets.
