/**
* @class vtkWriter
* @brief abstract class to write data to file(s)
*
* vtkWriter is an abstract class for mapper objects that write their data
* to disk (or into a communications port). All writers respond to Write()
* method. This method insures that there is input and input is up to date.
*
* @warning
* Every subclass of vtkWriter must implement a WriteData() method. Most likely
* will have to create SetInput() method as well.
