Multiple calls to cortix.run() in the same run file for the BWR example

[dealmeidavf]

A second run can be done directly. Note the modules brought back from the save option are available after plotting.
close() should not be issued. The network needs to be rebuilt. Modules need to be compatible a restart that will not run the constructor.
