/* * * * *
 * 
 * Extension file for the SimpleJSON framework for better support of some common
 * .NET types. It does only work together with the SimpleJSON.cs
 * It provides direct conversion support for types like decimal, char, byte,
 * sbyte, short, ushort, uint, DateTime, TimeSpan and Guid. In addition there
 * are conversion helpers for converting an array of number values into a byte[]
 * or a List<byte> as well as converting an array of string values into a string[]
 * or List<string>.
 * Finally there are some additional type conversion operators for some nullable
 * types like short?, int?, float?, double?, long? and bool?. They will actually
 * assign a JSONNull value when it's null or a JSONNumber when it's not.
