/**
* A JSONObject is an unordered collection of name/value pairs. Its external
* form is a string wrapped in curly braces with colons between the names and
* values, and commas between the values and names. The internal form is an
* object having get and opt methods for accessing
* the values by name, and put methods for adding or replacing
* values by name. The values can be any of these types: Boolean,
* JSONArray, JSONObject, Number,
* String, or the JSONObject.NULL object. A
* JSONObject constructor can be used to convert an external form JSON text
* into an internal form whose values can be retrieved with the
* get and opt methods, or to convert values into a
* JSON text using the put and toString methods. A
* get method returns a value if one can be found, and throws an
* exception if one cannot be found. An opt method returns a
* default value instead of throwing an exception, and so is useful for
* obtaining optional values.
*
* The generic get() and opt() methods return an
* object, which you can cast or query for type. There are also typed
* get and opt methods that do type checking and type
* coercion for you. The opt methods differ from the get methods in that they
* do not throw. Instead, they return a specified value, such as null.
*
* The put methods add or replace values in an object. For
* example,
*
*
* myString = new JSONObject()
* .put("JSON", "Hello, World!").toString();
*
*
* produces the string {"JSON": "Hello, World"}.
*
* The texts produced by the toString methods strictly conform to
* the JSON syntax rules. The constructors are more forgiving in the texts they
* will accept:
*
* - An extra
, (comma) may appear just
* before the closing brace.
* - Strings may be quoted with
' (single
* quote).
* - Strings do not need to be quoted at all if they do not begin with a
* quote or single quote, and if they do not contain leading or trailing
* spaces, and if they do not contain any of these characters:
*
{ } [ ] / \ : , # and if they do not look like numbers and
* if they are not the reserved words true, false,
* or null.

* Construct a JSONObject from an Object using bean getters. It reflects on

* parameters and a name starting with "get" or
* "is" followed by an uppercase letter, the method is invoked,
* and a key and the value returned from the getter method are put into the
* new JSONObject.
*
* The key is formed by removing the "get" or "is"
* prefix. If the second remaining character is not upper case, then the
* first character is converted to lower case.
*
* Methods that are static, return void,
* have parameters, or are "bridge" methods, are ignored.
*
* For example, if an object has a method named "getName", and
* if the result of calling object.getName() is
* "Larry Fine", then the JSONObject will contain
* "name": "Larry Fine".
*
* The {@link JSONPropertyName} annotation can be used on a bean getter to
* override key name used in the JSONObject. For example, using the object
* above with the getName method, if we annotated it with:
*
* @JSONPropertyName("FullName")
* public String getName() { return this.name; }
*
* The resulting JSON object would contain "FullName": "Larry Fine"
*
* Similarly, the {@link JSONPropertyName} annotation can be used on non-
* get and is methods. We can also override key
* name used in the JSONObject as seen below even though the field would normally
* be ignored:
*
* @JSONPropertyName("FullName")
* public String fullName() { return this.name; }
*
* The resulting JSON object would contain "FullName": "Larry Fine"
*
* The {@link JSONPropertyIgnore} annotation can be used to force the bean property
* to not be serialized into JSON. If both {@link JSONPropertyIgnore} and
* {@link JSONPropertyName} are defined on the same method, a depth comparison is
* performed and the one closest to the concrete class being serialized is used.
* If both annotations are at the same level, then the {@link JSONPropertyIgnore}
* annotation takes precedent and the field is not serialized.
* For example, the following declaration would prevent the getName
* method from being serialized:
*
* @JSONPropertyName("FullName")
* @JSONPropertyIgnore
* public String getName() { return this.name; }
