New structure for builder.
Initial work on restructuring EnsembleVertex.
Bugfix: renamed attributes.
Builder builds Ensembles.
Connections are added as Edges, constant node output is converted to direct current injection.
Include work by @tcstewar from EnsembleData.
Include constant inputs, write the bias region.
Write encoders region.
Bugfix: Switch between regions.
Correction to REGIONS reference.
Initial stab at getting decoder and output keys sorted.
generate_routing_info returns a tuple.
Correctly deal with random states.
Only find prevertices for Nodes which have been assigned an Rx component.
Made variables dt, timestep more explicit and factored dt into one_over_tau_rc (renamed).
Starting work on Nodes and Tx component.
Keep track of rx and tx assignations, ensure that tx and rx components are added to the DAO, return the DAO when done.
Base ReceiveVertex on TransmitVertex.
Added Builder variables to the DAO.
Initial tests.
