Implements	`osid.OsidCompendium`
Used By	`osid.mapping.path.MyPathSession`
	`osid.mapping.path.ResourceVelocityList`
	`osid.mapping.path.ResourceVelocitySession`
Description	A `Velocity` for a `Resource`.
Method	getResourceId
Description	Gets the `Resource` `Id`.
Return	`osid.id.Id`		the resource `Id`
Compliance	`mandatory`		This method must be implemented.
Method	getResource
Description	Gets the `Resource`.
Return	`osid.resource.Resource`		the resource
Errors	OPERATION_FAILED		unable to complete request
Compliance	`mandatory`		This method must be implemented.
Method	getSpeed
Description	Gets the current speed.
Return	`osid.mapping.Speed`		the current speed
Compliance	`mandatory`		This method must be implemented.
Method	getPosition
Description	Gets the current position.
Return	`osid.mapping.Coordinate`		the current coordinate
Compliance	`mandatory`		This method must be implemented.
Method	getHeading
Description	Gets the current heading.
Return	`osid.mapping.Heading`		the current heading
Compliance	`mandatory`		This method must be implemented.
Method	isOnPath
Description	Tests if the resource is on a designated path.
Return	`boolean`		`true` if the resource is on a designated path, `false` otherwise
