     * What is a PCF file? http://www.alias.ltd.uk/pcf.asp
     *
     * The Piping Component File (PCF) is the primary input for Personal ISOGEN. PCFs are 
     * text files containing component and routing information. For each component, they will 
     * include various mandatory records to define the basic information of:
     *   + Type ¨C Flange, pipe, or valve, for example
     *   + Coordinates and size of the end-points
     *   + Shape (SKEY) to be used to represent the component on the isometric
     * PCFs are created by the piping design system extracting information from the piping 
     * model. A single PCF can contain the data for a number of pipelines, but generally, the 
     * piping design system extracts piping data for single pipelines only.Then Personal ISOGEN 
     * will produce isometrics for one pipeline at a time.
