/** \class CSVArray2DFileReader
* \brief Parses csv files and stores the data in a itkCSVArray2DDataObject.
*
* CSVArray2DFileReader is used for reading csv files. This reader should
* only be used for parsing numeric data fields. The Parse() method in this
* class parses the data from the file into a itkCSVArray2DDataObject. As the
* Array2D object only holds one data type, all the data, other than the row
* and column headers, will be cast to a single data type. Row and column
* headers will be parsed into std vectors of strings.
*
* The user would need to specify the file name using the SetFileName() method.
* The field delimiter character is set to ',' by default but other field
* delimiter characters may be set using SetFieldDelimiterCharacter(). If there
* are row and column headers in the file, the user must specify whether or not
* they exist using the HasRowHeaders and HasColumnHeaders flags. Also, if row
* and/or column headers are enclosed in "" or within other string delimiter
* characters being used, the user can set the option of turning the string
* delimiter character on with the UseStringDelimiterCharacter flag. This is
* also especially useful if headers such as "This,Header" contain commas or
* other field delimiter characters within them.
*
* If the csv file has row and column headers, they do not necessarily need to
* be enclosed in "" or other string delimiter characters as long as you
* specify that row and/or column headers exist in the file. Turning on
* HasColumnHeaders flags will tell the reader that the first line contains
* column headers and turning on HasRowHeaders will tell the reader to
* recognize the first field in all subsequent lines as row headers. After all
* the inputs have been set, the user then calls the Parse() method. The user
* can then get the results by instantiating a itkCSVArray2DDataObject and
* assigning it using the GetOutput() method.
*
* Below is an example of how this class can be used to read and parse the data
* from an input file:
*
* typedef itk::CSVArray2DFileReader<double> ReaderType;
* ReaderType::Pointer reader = ReaderType::New();
*
* std::string filename = "NameOfFile.csv";
* reader->SetFileName( filename );
* reader->SetFieldDelimiterCharacter( ',' );
* reader->SetStringDelimiterCharacter( '"' );
* reader->HasColumnHeadersOn();
* reader->HasRowHeadersOn();
* reader->UseStringDelimiterCharacterOn();
*
* reader->Parse();
*
