Detailed Description

Loads a connection matrix from a file and creates a neuron group and connection group. The matrix must be square or an error will be thrown. The neuron group is created with the first type of neuron and synapse in the database and starting at position 0, 0, 0. Will try and make the neuron group as close to square as possible. FIXME NEED A DIALOG TO SPECIFY THE DETAILS PROPERLY. FIXME THIS METHOD HAS NOT BEEN PROPERLY TESTED.
