/************************************************************
NAME : ParseSlot
DESCRIPTION : Parses slot definitions for a
defclass statement
INPUTS : 1) The logical name of the input source
2) The current slot list
3) The class precedence list for the class
to which this slot is being attached
(used to find facets for composite slots)
4) A flag indicating if this is a multifield
slot or not
5) A flag indicating if the type of slot
(single or multi) was explicitly
specified or not
RETURNS : The address of the list of slots,
NULL if there was an error
SIDE EFFECTS : The slot list is allocated
NOTES : Assumes "(slot" has already been parsed.
