// \brief read an image from a file
//
// vil_load returns a pointer to the base class of an vil_image_view object.
// You can then cast, or assign it to the appropriate type. You must not forget to
// delete the created view.
//
// vil_load_image_resource() returns a smart pointer to vil_image_resource which
// will "read an image from a file". In practice
// it may or may not read the image on creation, but a disk read will take place at
// some point before get_view() returns.
