iOS：链式编程-富文本

由于项目经常使用富文本，所以对富文本NSMutableAttributedString进行封装，思路仿照masonry的方式。

调用方式：

    UILabel* label = [[UILabel alloc] initWithFrame:CGRectMake(70, 100, 200, 500)];
    label.text = @"1234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890123456789012345678901234567890";
    label.numberOfLines = 0;
    [self.view addSubview:label];
        
    label.attributedText = [label.text cc_Attributed:^(ccAttributed * _Nonnull make) {
        make.cc_lineSpacing(20).cc_textAlignment(NSTextAlignmentLeft).cc_lineBreakMode(NSLineBreakByCharWrapping);
    }];

.h
