* This is an example of how you can create a custom CoordinateSequence class that wraps
* your own way of storing lists of coordinates. Depending on your internal storage
* format some methods in the wrapper class might not work properly (but have to be
* preserved for the interface compatibility. In this example CustomPointCoordinateSequence
* wraps an array of point_3d. Since the array is fixed length, methods like 'add' or
* 'deleteAt' will not work.
