class Settings:
	:class:`Settings` provides a way to define and access settings in a hierarchical fashion. The value of a setting can \
	be defined for each hierarchical level, where each level overrides the preceding level. The backing-store for setting \
	values at each level is also configurable. This allows for ephemeral or platform-independent persistent settings storage \
	for components within Binary Ninja or consumers of the Binary Ninja API.
	Each :class:`Settings` instance has an ``instance_id`` which identifies a schema. The schema defines the settings contents  \
	and the way in which settings are retrieved and manipulated. A new :class:`Settings` instance defaults to using a value of *'default'* \
	for the ``instance_id``. The *'default'* settings schema defines all of the settings available for the active Binary Ninja components \
	which include at a minimum, the settings defined by the Binary Ninja core. The *'default'* schema may additionally define settings \
	for the UI and/or installed plugins. Extending existing schemas, or defining new ones is accomplished by calling :func:`register_group` \
	and :func:`register_setting` methods, or by deserializing an existing schema with :func:`deserialize_schema`.
	.. note:: All settings in the *'default'* settings schema are rendered with UI elements in the Settings View of Binary Ninja UI.
	Allowing setting overrides is an important feature and Binary Ninja accomplishes this by allowing one to override a setting at various \
	levels. The levels and their associated storage are shown in the following table. Default setting values are optional, and if specified, \
	saved in the schema itself.
		================= ========================== ============== ==============================================
		Setting Level     Settings Scope             Preference     Storage
		================= ========================== ============== ==============================================
		Default           SettingsDefaultScope       Lowest         Settings Schema
		User              SettingsUserScope          -              <User Directory>/settings.json
		Project           SettingsProjectScope       -              <Project Directory>/settings.json
		Resource          SettingsResourceScope      Highest        Raw BinaryView (Storage in BNDB)
		================= ========================== ============== ==============================================
	Settings are identified by a key, which is a string in the form of **'<group>.<name>'** or **'<group>.<subGroup>.<name>'**. Groups provide \
	a simple way to categorize settings. Sub-groups are optional and multiple sub-groups are allowed. When defining a settings group, the \
	:func:`register_group` method allows for specifying a UI friendly title for use in the Binary Ninja UI. Defining a new setting requires a \
	unique setting key and a JSON string of property, value pairs. The following table describes the available properties and values.

	.. note:: In order to facilitate deterministic analysis results, settings from the *'default'* schema that impact analysis are serialized \
	from Default, User, and Project scope into Resource scope during initial BinaryView analysis. This allows an analysis database to be opened \
	at a later time with the same settings, regardless if Default, User, or Project settings have been modified.
	.. note:: Settings that do not impact analysis (e.g. many UI settings) should use the *"ignore"* property to exclude \
		*"SettingsProjectScope"* and *"SettingsResourceScope"* from the applicable scopes for the setting.
	Example analysis plugin setting:
		>>> my_settings = Settings()
		>>> title = "My Pre-Analysis Plugin"
		>>> description = "Enable extra analysis before core analysis."
		>>> properties = f'{{"title" : "{title}", "description" : "{description}", "type" : "boolean", "default" : false}}'
		>>> my_settings.register_group("myPlugin", "My Plugin")
		>>> my_settings.register_setting("myPlugin.enablePreAnalysis", properties)
		>>> my_bv = load("/bin/ls", options={'myPlugin.enablePreAnalysis' : True})
		>>> Settings().get_bool("myPlugin.enablePreAnalysis")
		>>> Settings().get_bool("myPlugin.enablePreAnalysis", my_bv)
	Example UI plugin setting:
		>>> my_settings = Settings()
		>>> title = "My UI Plugin"
		>>> description = "Enable My UI Plugin table display."
		>>> properties = f'{{"title" : "{title}", "description" : "{description}", "type" : "boolean", "default" : true, "ignore" : ["SettingsProjectScope", "SettingsResourceScope"]}}'
		>>> my_settings.register_group("myPlugin", "My Plugin")
		>>> my_settings.register_setting("myPlugin.enableTableView", properties)
		>>> my_bv = load("/bin/ls", options={'myPlugin.enableTableView' : True})
