Name    CFD objectline --- create the line object 
                           (Non-fluid Area) for CFD

Summary
   Name           CFD objectline
   Type           mapper
   Inputs         field 3D 3-space scalar real irregular
   Outputs        geometry

   Parameters     Name       Type      Default     Min/Max
                  On/Off     boolean   on          on/off

Description
   The "CFD objectline" module inputs a scalar field and 
   creates a line geometry (obstacle) for CFD data. 
   This module tells which digit (0 or 1) in the node as 
   flag data. 
   The flag data is as follows. 
   1 means the fluid node and 0 is the non-fluid node.

       1---1---1
       +   +   +
       0---0---1           +---+
       +   +   +   ---->   |   |    Non-fluid Area
       0---0---1           +---+    creates outline

       data(i,j,k) = the flag data for CFD node
                        1 : fluid node     (live)  
                        0 : non-fluid node (obstacle)

Parameters
   On/Off               Determines the visible/invisible.

Example
   This example needs a sample data(sample.fld) in this directory.

                      read_field                read sample2.fld
                         |
