Message:

Add a method to save Positions into a file. Polish and test the new Connector2 module, by adding a connectors_benchmark script in the unittest that allow to plot graphs of the connections for all the connectors and according to all the parameters. Need to play a bit with, but everything seems to be OK. Andrew, maybe please have a small look, and as soon as you consider that the progress bar, the connections are ok for you, you can commit the new connectors2 module and erase the old one.
