		Helper class to handle INI-style files.
	</brief_description>
	<description>
		This helper class can be used to store [Variant] values on the filesystem using INI-style formatting. The stored values are identified by a section and a key:
		[codeblock]
		[section]
		some_key=42
		string_example="Hello World!"
		a_vector=Vector3( 1, 0, 2 )
		[/codeblock]
		The stored data can be saved to or parsed from a file, though ConfigFile objects can also be used directly without accessing the filesystem.
		The following example shows how to parse an INI-style file from the system, read its contents and store new values in it:
		[codeblock]
		var config = ConfigFile.new()
		var err = config.load("user://settings.cfg")
		if err == OK: # If not, something went wrong with the file loading
		    # Look for the display/width pair, and default to 1024 if missing
		    var screen_width = config.get_value("display", "width", 1024)
		    # Store a variable if and only if it hasn't been defined yet
		    if not config.has_section_key("audio", "mute"):
		        config.set_value("audio", "mute", false)
		    # Save the changes by overwriting the previous file
		    config.save("user://settings.cfg")
		[/codeblock]
		Keep in mind that section and property names can't contain spaces. Anything after a space will be ignored on save and on load.

				Assigns a value to the specified key of the specified section. If the section and/or the key do not exist, they are created. Passing a [code]null[/code] value deletes the specified key if it exists, and deletes the section if it ends up empty once the key has been removed.
