Class to grab (ie. read) images from the disk.
Defined a virtual video device. "Grab" the images from the disk. Derived from the vpFrameGrabber class.
Here an example of capture from the directory "/local/soft/ViSP/ViSP-images/cube". We want to acquire 10 images from the first named "image.0001.pgm" by steps of 2.
