NOTE: running the yp-client code requires that the netconfd-pro server is built
with pthreads=1 or that you are running one of the pthreads binary servers.

The libtest.cpp example code shows an example of creating a library of modules,
users, and devices.

The code shows the following:

* create a library object from a known location
* create a collection of modules
* add the modules to the library, notify if the addition was a success or not
* create a set of users
* save the set to a file
* load the set from the file
* create a set of devices
* save the set to a file
* load the set from the file
