#### Procedure
       void wninsd_c ( SpiceDouble     left,
                       SpiceDouble     right,
                       SpiceCell     * window )
#### Abstract
       Insert an interval into a double precision window.

       VARIABLE  I/O  DESCRIPTION
       --------  ---  --------------------------------------------------
       left,
       right      I   Left, right endpoints of new interval.
       window    I,O  Input, output window.
#### Detailed_Input
       left,
       right       are the left and right endpoints of the interval
                   to be inserted.

       window      on input, is a CSPICE window containing zero or more
                   intervals.

                   window must be declared as a double precision
                   SpiceCell.
#### Detailed_Output
       window      on output, is the original window following the
                   insertion of the interval from left to right.
#### Parameters
       None.
#### Exceptions
       1) If the input window does not have double precision type,
          the error SPICE(TYPEMISMATCH) is signaled.

       2) If left is greater than right, the error SPICE(BADENDPOINTS) is
          signaled.

       3) If the insertion of the interval causes an excess of elements,
          the error SPICE(WINDOWEXCESS) is signaled.
#### Files
       None.
#### Particulars
       This routine inserts the interval from left to right into the
       input window. If the new interval overlaps any of the intervals
       in the window, the intervals are merged. Thus, the cardinality
       of the input window can actually decrease as the result of an
       insertion. However, because inserting an interval that is
       disjoint from the other intervals in the window can increase the
       cardinality of the window, the routine signals an error.

       No other CSPICE unary window routine can increase the number of
       intervals in the input window.
#### Examples
        Let window contain the intervals

           [ 1, 3 ]  [ 7, 11 ]  [ 23, 27 ]

        Then the following series of calls

           wninsd_c ( 5.0,  5.0, &window )                  (1)
           wninsd_c ( 4.0,  8.0, &window )                  (2)
           wninsd_c ( 0.0, 30.0, &window )                  (3)

        produces the following series of windows

           [ 1,  3 ]  [ 5,  5 ]  [  7, 11 ]  [ 23, 27 ]     (1)
           [ 1,  3 ]  [ 4, 11 ]  [ 23, 27 ]                 (2)
           [ 0, 30 ]                                        (3)
