Package: csv_file_reader_pkg

Define operations to read formatted data from a comma-separated-values file
(CSV file). To use this package:
1. Create a csv_file_reader: variable csv: csv_file_reader_type;
2. Open a csv file: csv.initialize("c:\file.csv");
3. Read one line at a time: csv.readline;
4. Start reading values: my_integer := csv.read_integer;
5. To read more values in the same line, call any of the read_* functions
6. To move to the next line, call csv.readline() again
