Tools to easily jsonify (fromJson/toJson) objects.

#Usage Instanciate [Jsonifier](jsonifiers:[...]) class and use its methods [Jsonifier.fromJson] and [Jsonifier.toJson]. [Jsonifier] can serialize this types :

• Scalar Json types : null, String, int, double, bool.
• Dart bases types : DateTime, Duration, UInt8List.
• Any type covered by [TypeJsonifier]s provided in the jsonifiers parameter of the contructor.
• Structured types : Map<String, T>, List, Set and Iterable where T is any of types enumerated here.
• Any T? where T is any of the preceding types or combination (eg. Set<int?>?, Iterable<String?>, ...).

#How to serialize Enum (or types referencing enums). To serialize enum types, provide the jsonifiers parameter of the [Jsonifier] constructor, filled with [EnumJsonifier] instance(s). Once provided, these enums can be used as any base types.

#How to serialize other types For a class C to be serializable, provide the jsonifiers parameter to the [Jsonifier] constructor, filled with [ClassJsonifier] or [StringEncodeJsonifier] instance(s). Once provided, the type C can be used as any base types.

[StringEncodeJsonifier] is intended for classes with simple data to serialize (eg. DateTime) witch can have a simple string representation. Extending [StringEncodeJsonifier] involves overriding its toJson and fromJson methods to provide a string representation of the state of C and rebuilding an instance of C from this encoded string value.

[ClassJsonifier] is intended for classes with complex structure. Ist fromJson/toJson methods receive/return a Map<String,dynamic> (typedef [JsonMap]) containing the class state. Extension [JsonMapExtension] provide methods on [JsonMap] to facilitate typed reads to properties in fromJson implementation. Encoding and decoding of [JsonMap] entries are automaticaly done by [Jsonifier].
