Recurrent spiking neural network to simulate the consolidation of memory representations based on synaptic tagging and capture

• functionality and shell scripts have been added for
  • simulations with randomly initialized weights
  • investigations on the frequency dependence of LTP and LTD
  • attractor memory representations
• dependence of protein synthesis thresholds on neuromodulator amount has been added
• analysis scripts such as averageFileColumnsAdvanced.py have received upgrades
• weight units have been changed to mV
• several bugs have been fixed
