> 1. update the java docs for IDF apis.
> 2.  Make the getTextData final and call it getCSV and setCSV, so it is obvious that we
want to enforce CSV format
>  the following code can move to the base class IntermediateDataFormat and made final,
so there is no way to override this and we can enforce all to return String instead of generic
T
> {code}
> // hold the string in IDF base class
>  private final String text.
>  
>   public final String getCSVTextData() {
>     return text;
>   }
>  
>   public final void setCSVTextData(String text) {
>     this.text = text;
>   }
> {code}
> There is code in CSVIDF implementation that has the rules for CSV parsing that can be
pulled out into CSV Utils so that the connectors can use
> The T in CSV happens to String, which is just a coincidence, If I write a new IDF implementation
T can be a custom object that could encapsulate the whole row.
> Third, getData and setData can have custom implementation so they can be overriden to
return the generic type T
> Correction :
> {code}
> // hold the string in IDF base class, is !final
>  private String text.
>  
>   public final String getCSVTextData() {
>     return text;
>   }
>  
>   public final void setCSVTextData(String text) {
>     this.text = text;
>   }
> {code}
