the example restarts correctly.

affine layers was changed so to use the same conventions as other layers that
support convolutional vs fully connected modes.

to caffe models.  Not all layers are supported yet, but it works on the net
from the first dlib dnn example program.  Will add the rest of the layers soon.

you to ask for attributes that don't exist and get a defined behavior (an
exception being thrown) rather than it being a contract violation.

* Use GNUInstallDirs to allow changing target directories

* Multi-lib distributions need to change the libdir
  which is only portably possible with `GNUInstallDirs`.
  The current `LIB_INSTALL_DIR` solution is not portable
  and not supported upstream by Kitware.
* Multi-arch distributions such as Debian and Exherbo
  need to be able to change the bindir.

* Do not install LICENSE.txt

* Most distributions do not install license files, as they
  have all licenses stored in a central repository, in order
  not to duplicate the same file over and over.
* License files do not need to be installed for a piece of
  software to be licensed under that license.
