#### Procedure
       void removd_c ( SpiceDouble     item,
                       SpiceCell     * set  )
#### Abstract
       Remove an item from a double precision set.
#### Required_Reading
       SETS
#### Keywords
       CELLS, SETS
#### Brief_I/O
       VARIABLE  I/O  DESCRIPTION
       --------  ---  --------------------------------------------------
       item       I   Item to be removed.
       set       I/O  Removal set.
#### Detailed_Input
       item        is an item which is to be removed from the specified
                   set. item may or may not already be an element of the
                   set.

       set         is a CSPICE set.  set must be declared as a double
                   precision SpiceCell.

                   On input, set may or may not contain the input item
                   as an element.
#### Detailed_Output
       set         on output contains the difference of the input set and
                   the input item. If the item is not an element of the
                   set, the set is not changed.
#### Parameters
       None.
#### Exceptions
       1) If the input set argument is a SpiceCell of type other than
          double precision, the error SPICE(TYPEMISMATCH) is signaled.

       2) If the input set argument does not qualify as a CSPICE set,
          the error SPICE(NOTASET) will be signaled.  CSPICE sets have
          their data elements sorted in increasing order and contain
          no duplicate data elements.
#### Files
       None.
#### Particulars
       None.
#### Examples
       1) In the following code fragment, a list of camera exposure
          durations are taken from the array expList and inserted into the
          set expDur.

          We then update the set by removing the element 30.0 and
          inserting 20.0 in its place.

             #include "SpiceUsr.h"
                    .
                    .
                    .
             /.
             The number of list items is NLIST.
             ./
             SpiceDouble        expList[NLIST] =
                                {
                                   0.5, 2.0, 0.5, 30.0, 0.01, 30.0
                                };

             /.
             Declare the set with maximum number of elements MAXSIZ.
             ./
             SPICEDOUBLE_CELL ( expDur,   MAXSIZ );
                    .
                    .
                    .
             for ( i = 0;  i < NLIST;  i++ )
             {
                insrtd_c ( expList[i], &expDur );
             }

             /.
             At this point expDur contains the set

               { 0.01, 0.5, 2.0, 30.0 }

             ./
                    .
                    .
                    .
             /.
             Update the exposure set by replacing 30.0 with 20.0.
             ./
             removd_c ( 30.0, &expDur );
             insrtd_c ( 20.0, &expDur );
