DirectionParameters class

Represents the parameters for a direction request in the Google Maps Embed API.

The DirectionParameters class extends the Parameters class and provides additional properties and methods specific to direction requests.

The direction request requires an origin and a destination, and can optionally include waypoints, direction mode, avoids, and units.

The maximum number of waypoints allowed in a direction request is defined by the constant kMaxWaypoints.
