	GetInstalledPlugIns
	GetLicense(LicenseBuildType, ValidateProductKeyDelegate)	Verifies that there is a valid product license for your plug-in, using the Rhino licensing system. If the plug-in is installed as a standalone node, the locally installed license will be validated. If the plug-in is installed as a network node, a loaner license will be requested by the system's assigned Zoo server. If the Zoo server finds and returns a license, then this license will be validated. If no license is found, then the user will be prompted to provide a license key, which will be validated.
	GetLicense(LicenseBuildType, ValidateProductKeyDelegate, OnLeaseChangedDelegate)	Verifies that there is a valid product license for your plug-in, using the Rhino licensing system. If the plug-in is installed as a standalone node, the locally installed license will be validated. If the plug-in is installed as a network node, a loaner license will be requested by the system's assigned Zoo server. If the Zoo server finds and returns a license, then this license will be validated. If no license is found, then the user will be prompted to provide a license key, which will be validated.
	GetLicense(LicenseCapabilities, String, ValidateProductKeyDelegate)	Verifies that there is a valid product license for your plug-in, using the Rhino licensing system. If the plug-in is installed as a standalone node, the locally installed license will be validated. If the plug-in is installed as a network node, a loaner license will be requested by the system's assigned Zoo server. If the Zoo server finds and returns a license, then this license will be validated. If no license is found, then the user will be prompted to provide a license key, which will be validated.
	GetLicense(LicenseCapabilities, String, ValidateProductKeyDelegate, OnLeaseChangedDelegate)	Verifies that there is a valid product license for your plug-in, using the Rhino licensing system. If the plug-in is installed as a standalone node, the locally installed license will be validated. If the plug-in is installed as a network node, a loaner license will be requested by the system's assigned Zoo server. If the Zoo server finds and returns a license, then this license will be validated. If no license is found, then the user will be prompted to provide a license key, which will be validated.
	GetLicenseOwner	Get the customer name and organization used when entering the product license.
	GetLoadProtection	Get load protection state for a plug-in
	GetPlugInInfo	Returns detailed information about an installed Rhino plug-in.
	GetPlugInObject

	IdFromName	Gets the id of an installed plug-in giving the plug-in's name.
	IdFromPath	Gets the id of an installed plug-in giving the plug-in's file path.
	LoadPlugIn(Guid)	Loads an installed plug-in.
	LoadPlugIn(String, Guid)	Attempt to load a plug-in at a path. Loaded plug-ins are remembered by Rhino between sessions, so this function can also be considered a plug-in installation routine
	LoadPlugIn(Guid, Boolean, Boolean)	Loads an installed plug-in.

	PathFromName	Gets the path to an installed plug-in given the name of that plug-in
	PlugInExists	Verifies that a Rhino plug-in is installed.
	RaiseOnPlugInSettingsSavedEvent	Raise any pending OnPlugInSettingsSaved events, the events are normally queued while a command is running and and fired while Rhino is in an idle state. Calling this method will raise any pending changed events regardless of Rhino's current idle state or if a command is running.
	ReadDocument	Called whenever a Rhino document is being loaded and plug-in user data was encountered written by a plug-in with this plug-in's GUID.
	RegisterCommand
	ResetMessageBoxes
	ReturnLicense	Returns, or releases, a product license that was obtained from the Rhino licensing system. Note, most plug-ins do not need to call this as the Rhino licensing system will return all licenses when Rhino shuts down.
	SavePluginSettings
	SaveSettings	Write settings to disk which will raise a SettingsSaved event.
	SetLicenseCapabilities
	SetLoadProtection	Set load protection state for a certain plug-in
	ShouldCallWriteDocument	Called whenever a Rhino is about to save a .3dm file. If you want to save plug-in document data when a model is saved in a version 5 .3dm file, then you must override this function to return true and you must override WriteDocument().
	ToString	(Inherited from Object.)
	WriteDocument	Called when Rhino is saving a .3dm file to allow the plug-in to save document user data.
