Setting options for parser requires creating a custom delegate

[johnthuss]

It's very cumbersome to use the parser when you want to modify the options (in this case, set sanitizesFields). Instead of just calling [@"a,b,c" CSVComponents] you have to create an entire delegate class from scratch and pass it to the parser. You should provide a default delegate, like CHCSVAccumulatorDelegate.

Another sugary option for the string category would be to allow options to be passed in:

@implementation NSString (CHCSVAdditions)

- (NSArray *)CSVComponentsWithOptions:(NSDictionary *)options {
    _CHCSVAggregator *aggregator = [[_CHCSVAggregator alloc] init];
    CHCSVParser *parser = [[CHCSVParser alloc] initWithCSVString:self];
    [parser setDelegate:aggregator];
    for (NSString *key in [options keys])
         [parse takeValue:options[key] forKey:key];
    [parser parse];
    CHCSV_RELEASE(parser);

    NSArray *final = CHCSV_AUTORELEASE(CHCSV_RETAIN([aggregator lines]));
    CHCSV_RELEASE(aggregator);

    return final;
}

@end

I'll take a look at this. Thanks for the suggestion!

I went with a bitfield instead of an NSDictionary. It seemed more idiomatic that way.
