/**
* @class vtkFixedWidthTextReader
* @brief reader for pulling in text files with fixed-width fields
*
*
*
* vtkFixedWidthTextReader reads in a table from a text file where
* each column occupies a certain number of characters.
*
* This class emits ProgressEvent for every 100 lines it reads.
*
*
* @warning
* This first version of the reader will assume that all fields have
* the same width. It also assumes that the first line in the file
* has at least as many fields (i.e. at least as many characters) as
* any other line in the file.
*
* @par Thanks:
* Thanks to Andy Wilson from Sandia National Laboratories for
* implementing this class.
