@trwegner done, enjoy!

thanks @austinlparker. wondering if there are objections to also converting to use nameof() in these methods to eliminate literal string for class and member names:

    public override string ToString()
    {
        return "Status{"
                + "canonicalCode=" + this.CanonicalCode + ", "
                + "description=" + this.Description
                + "}";
    }

would change to

    public override string ToString()
    {
        return nameof(Status) + "{"
                + nameof(this.CanonicalCode) + "=" + this.CanonicalCode + ", "
                + nameof(this.Description) + "=" + this.Description
                + "}";
    }

works for me

I believe this was fixed in some clean up round. There are no more Collections utils
