Ceylon JSON object representation

This project is based and in general is similar to SDK module ceylon.json. In contrast with SDK it contains mutable and immutable JSON object and array.

####JSON value Value JSON operates with: String | Boolean | Integer | Float | JsonObject | JsonArray | Null

####JSON Object JSON object is enumerated with three states: mutable, immutable and empty:

  shared interface JsonObject
      of MutableJsonMap | JsonMap | EmptyJsonMap
      satisfies Map<String, JsonValue>

• MutableJsonMap is mutable JSON object and it is very similar to SDK ceylon.json.object. Any embeded objects and arrays mutable object contains are mutable. If immutable sub-item passed to mutable object it is converted to mutable internaly.
• JsonMap is immutable JSON object. It can be filled only at initialization. JsonMap contains only immutable embeded JSON objects and arrays. If mutable sub-item passed to initializer it is converted to immutable internaly.
• EmptyJsonMap is immutable and represents object which is always empty.

####JSON Array JSON array structure is similar to JSON object:

shared interface JsonArray
    of MutableJsonList | JsonList | EmptyJsonList
    satisfies List<JsonValue>
