MovementCategorizer mc = new MovementCategorizer();
// ^^ creates a new MovementCategorizer with default settings

/// MovementCategorizer mc = new MovementCategorizer(path);
// ^^ creates a new MovementCategorizer that uses images from the 
// specified path. Images should be in PNG or BMP format

// If a path is specified, the required images with their correct filenames must be present.

// You can obtain schematic information from a Movement, mv, using
MovementDescription md = mc.GetMovementDescription(mv);
String filename = mc.GetFilename(mv);
Image img = mc.GetImage(mv);
The following working example illustrates the use of MovementCategorizer's GetImage(Movement), GetFilename(Movement) and GetMovementDescription(Movement) methods.
// Create a MovementCategorizer with defaults and look for images in the
// Program Files\Telogis\GeoBase\GeoBaseResources\TurnIcons folder.
MovementCategorizer mc = new MovementCategorizer();

// Create a MovementCategorizer that points to the specified image folder.
// This folder must contain all images with their correct file names.
// MovementCategorizer mc = new MovementCategorizer(@"C:\path_to_folder\TurnIcons");
