/**
* Use this builder to construct a {@link Gson} instance when you need to set configuration
* options other than the default. For {@link Gson} with default configuration, it is simpler to
* use {@code new Gson()}. {@code GsonBuilder} is best used by creating it, and then invoking its
* various configuration methods, and finally calling create.
*
* The following is an example shows how to use the {@code GsonBuilder} to construct a Gson
* instance:
*
*
* Gson gson = new GsonBuilder()
* .registerTypeAdapter(Id.class, new IdTypeAdapter())
* .enableComplexMapKeySerialization()
* .serializeNulls()
* .setDateFormat(DateFormat.LONG)
* .setFieldNamingPolicy(FieldNamingPolicy.UPPER_CAMEL_CASE)
* .setPrettyPrinting()
* .setVersion(1.0)
* .create();
*
*
* NOTES:
*
* - the order of invocation of configuration methods does not matter.
* - The default serialization of {@link Date} and its subclasses in Gson does
* not contain time-zone information. So, if you are using date/time instances,
* use {@code GsonBuilder} and its {@code setDateFormat} methods.

* For this case, assume that a type adapter is registered to serialize and
* deserialize some {@code Point} class, which contains an x and y coordinate,
* to/from the JSON Primitive string value {@code "(x,y)"}. The Java map would
* then be serialized as a {@link JsonObject}.
*

{@code
* Gson gson = new GsonBuilder()
* .register(Point.class, new MyPointTypeAdapter())
* .enableComplexMapKeySerialization()
* .create();
*
* Map original = new LinkedHashMap();
* original.put(new Point(5, 6), "a");

* {
* "(5,6)": "a",
* "(8,8)": "b"
* }
* }
*
* Maps as JSON arrays
* For this case, assume that a type adapter was NOT registered for some
* {@code Point} class, but rather the default Gson serialization is applied.
* In this case, some {@code new Point(2,3)} would serialize as {@code
* {"x":2,"y":5}}.
*
* Given the assumption above, a {@code Map} will be
* serialize as an array of arrays (can be viewed as an entry set of pairs).

*
{@code
* Gson gson = new GsonBuilder()
* .enableComplexMapKeySerialization()
* .create();
*
* Map original = new LinkedHashMap();
* original.put(new Point(5, 6), "a");
* original.put(new Point(8, 8), "b");
* System.out.println(gson.toJson(original, type));
* }
*
* The JSON output would look as follows:
