title: Unmarshal JSON to Map/List of Strings
body: <p>I would like to unmarshal a Json to a Map/List of Strings (eg Map>...) </p>
  
  <p>Here is my input:</p>
  
  <pre><code>{"pointsOfSale": 
  {"pointOfSale":[ 
  {"href":"\/pointsOfSale\/UUID.0abc2aca-7930-4c9e-9f38-8af3d0692e04", 
  "model":{"href":"\/models\/modelePointOfSale", 
  "modelType":{"href":"\/modelTypes\/pointOfSale"}}, 
  "source":{"href":"\/sources\/TEST"}, 
  "attribute":[ 
  {"code":"pointOfSalePhysical","value":true}, 
  {"code":"mail","value":"Mail1"}, 
  {"code":"adresse","value":"address1"}]}, 
  {"href":"\/pointsOfSale\/UUID.a12e7adf-652a-4197-91bf-d4785e43f09f", 
  "model":{"href":"\/models\/modelePointOfSale", 
  "modelType":{"href":"\/modelTypes\/pointOfSale"}}, 
  "source":{"href":"\/sources\/Wikeo"}, 
  "attribute":[ 
  {"code":"pointOfSalePhysical","value":false}, 
  {"code":"mail","value":"Mail1"}, 
  {"code":"adresseMateriau","value":"Material address1"}]} 
  }}
  </code></pre>
  
  <p>I would like to be able to do "something" like this after unmarshaling: </p>
  
  <pre><code>myJsonMapped.get("pointsOfSale").get("pointOfSale").get(0).get("source").get("href").equals("\/sources\/TEST") == true 
  </code></pre>
  
  <p>For instance, with Gson we can do this kind of decoding: </p>
  
  <pre><code>new Gson().fromJson(json, Map.class); 
  </code></pre>
  
  <p>I know I can do this with a simple bean or processor etc... </p>
  
  <p>I just want to know of I can do this more efficiently with a native JSON camel component config </p>
  
  <p>EDIT: I tried different thing already like : 
  unmarshal().json()... 
  or 
  unmarshal().json(JsonLibrary.Gson, Map.class).. 
  etc... 
  without succes :'(</p>
