// .NAME vtkFixedWidthTextReader - reader for pulling in text files with fixed-width fields
//
// .SECTION Description
//
// 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.
//
// .SECTION Caveats
//
// 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.
//
// .SECTION Thanks
// Thanks to Andy Wilson from Sandia National Laboratories for
// implementing this class.
