Library for reading/writing CDB (Constant Database) files

```c#

class Program {

  static void Main(string[] args) {

    using (var writer = new StringCDBWriter("verses.cdb")) {

      foreach (var verse in parseVerses(new StreamReader(new GZipStream(new WebClient().OpenRead("https://s3.amazonaws.com/mongol.ephisys.com/Data/kjv.rawtxt.gz"), CompressionMode.Decompress)))) {

        writer.AddEntry(verse.Key, verse.Value);

      }

    }

    using (var cdb = new StringCDBReader("verses.cdb")) {

      Console.WriteLine(cdb.Find("John3:16").Single());

    }

  }

  private static IEnumerable> parseVerses(StreamReader sr) {

    // Iterator to return verses as long as we keep finding more.  Loads about 31,000 verses.

    while (!sr.EndOfStream) {

      var match = Regex.Match(sr.ReadLine(), @"(?\d*[A-Za-z]+\d+:\d+)\s(?.+$)");

      if (match.Success) {

        yield return new KeyValuePair(match.Groups["Reference"].Value, match.Groups["Verse"].Value);

      }

    }

  }

}
