Do the same as UIKit#recursiveDescription, but for CCNode instead of UIView

CCNode+RecursiveDescription.h

#import <Foundation/Foundation.h>
#import "CCNode.h"

@interface CCNode (RecursiveDescription)

- (NSString*)recursiveDescription;

@end

@implementation CCNode (RecursiveDescription)

- (NSString*)recursiveDescription
{
    return [self recursivelyListChildren:0];
}

- (NSString*)recursivelyListChildren:(NSUInteger)depth
{
    NSString * padding = @"";
    for(int i =0; i < depth;i++)
    {
        padding = [NSString stringWithFormat:@"%@ | ", padding];
    }

    NSString *description = [NSString stringWithFormat:@"%@%@", padding, self.description];
    NSMutableArray *children = [@[description] mutableCopy];

    for(CCNode * node in _children)
    {
        [children addObject:[node recursivelyListChildren:depth + 1]];
    }

    return [children componentsJoinedByString:@"\n"];
}
