This class can capture images from a remote webcam.

It takes the URL of a given remote webcam site and retrieve the current webcam image to a local file.

Retrieved images may be shrunk in case they exceed a give width or height limit.

The class can also check the remote Webcam image date to verify if it is newer than the previously retrieved webcam image.

Multiple webcam images may be archived in a local directory with file names based on the image retrieval timestamp.
