		Helper class for creating and parsing JSON data.
	</brief_description>
	<description>
		The [JSON] enables all data types to be converted to and from a JSON string. This useful for serializing data to save to a file or send over the network.
		[method stringify] is used to convert any data type into a JSON string.
		[method parse] is used to convert any existing JSON data into a [Variant] that can be used within Godot. If successfully parsed, use [method get_data] to retrieve the [Variant], and use [code]typeof[/code] to check if the Variant's type is what you expect. JSON Objects are converted into a [Dictionary], but JSON data can be used to store [Array]s, numbers, [String]s and even just a boolean.
		[b]Example[/b]
		[codeblock]
		var data_to_send = ["a", "b", "c"]
		var json_string = JSON.stringify(data_to_send)
		# Save data
		# ...
		# Retrieve data
		var error = json.parse(json_string)
		if error == OK:
		    var data_received = json.get_data()
		    if typeof(data_received) == TYPE_ARRAY:
		        print(data_received) # Prints array
		    else:
		        print("Unexpected data")
		else:
		    print("JSON Parse Error: ", json.get_error_message(), " in ", json_string, " at line ", json.get_error_line())
		[/codeblock]
		Alternatively, you can parse string using the static [method parse_string] method, but it doesn't allow to handle errors.
		[codeblock]
		var data = JSON.parse_string(json_string) # Returns null if parsing failed.

	<methods>
		<method name="get_data" qualifiers="const">
			<return type="Variant" />
			<description>
				Returns the [Variant] containing the data of a successful [method parse].
				[b]Note:[/b] It will return [code]Null[/code] if the last call to parse was unsuccessful or [method parse] has not yet been called.
			</description>
		</method>
		<method name="get_error_line" qualifiers="const">
			<return type="int" />
			<description>
				Returns [code]0[/code] if the last call to [method parse] was successful, or the line number where the parse failed.
			</description>
		</method>
		<method name="get_error_message" qualifiers="const">
			<return type="String" />
			<description>
				Returns an empty string if the last call to [method parse] was successful, or the error message if it failed.
			</description>
		</method>
		<method name="parse">
			<return type="int" enum="Error" />
			<param index="0" name="json_string" type="String" />
			<description>
				Attempts to parse the [param json_string] provided.
				Returns an [enum Error]. If the parse was successful, it returns [code]OK[/code] and the result can be retrieved using [method get_data]. If unsuccessful, use [method get_error_line] and [method get_error_message] for identifying the source of the failure.
				Non-static variant of [method parse_string], if you want custom error handling.
			</description>
		</method>
		<method name="parse_string" qualifiers="static">
			<return type="Variant" />
			<param index="0" name="json_string" type="String" />
			<description>
				Attempts to parse the [param json_string] provided and returns the parsed data. Returns [code]null[/code] if parse failed.
			</description>
		</method>
		<method name="stringify" qualifiers="static">
			<return type="String" />
			<param index="0" name="data" type="Variant" />
			<param index="1" name="indent" type="String" default="&quot;&quot;" />
			<param index="2" name="sort_keys" type="bool" default="true" />
			<param index="3" name="full_precision" type="bool" default="false" />
			<description>
				Converts a [Variant] var to JSON text and returns the result. Useful for serializing data to store or send over the network.
				[b]Note:[/b] The JSON specification does not define integer or float types, but only a [i]number[/i] type. Therefore, converting a Variant to JSON text will convert all numerical values to [float] types.
				[b]Note:[/b] If [param full_precision] is [code]true[/code], when stringifying floats, the unreliable digits are stringified in addition to the reliable digits to guarantee exact decoding.
				The [param indent] parameter controls if and how something is indented, the string used for this parameter will be used where there should be an indent in the output, even spaces like [code]"   "[/code] will work. [code]\t[/code] and [code]\n[/code] can also be used for a tab indent, or to make a newline for each indent respectively.
				[b]Example output:[/b]
				[codeblock]
				## JSON.stringify(my_dictionary)
				{"name":"my_dictionary","version":"1.0.0","entities":[{"name":"entity_0","value":"value_0"},{"name":"entity_1","value":"value_1"}]}
