/**
The `CSVFile` is a helper class to load and process tabular data which is stored in a text file.

The type of delimiter is auto-detected from the first lines of the file. Possible delimeters are `;`, `,`, a tabulator (\t) or space(s).

Lines beginning with `#` are and empty lines are ignored. Quotes around (`"`) values are removed. Both Linux (\n) and Windows (\r\n) line ending characters are supported.

All indices are 0-based (e.g., valid rows are 0..rowCount-1).

Example
-------

        var csv = new CSVFile(""); // do not load a file

        csv.loadFromString('a;b;c\n1;2;3\n1;4;12.1'); // note the newline characters
        console.log( csv.value(1,2) ); // -> 12.1

        // change a value
        csv.setValue(csv.rowCount-1,csv.columnIndex('a'), 100);
        csv.saveFile(Globals.path('temp/test.csv'));

        var csv = new CSVFile( Globals.path('temp/test.csv') );
        console.log( csv.value(1,"c") ); // -> 12.1
        console.log( csv.row(0) ); // get the full row (including delimiters)

        // loop over all rows
        for (var i=0;i<csv.rowCount;++i)
            console.log( csv.value(i,0) );
