Set of Projection classes
The set of Projection classes implements containers; each container contains synapses of one of the types supported by the synapse_traits module. Each synapse projection has a unique ID.
Projection classes store synapses, which are connections between the neurons in the presynaptic and postsynaptic populations. The IDs of these populations are stored in projection.
Using the set of Projection classes, you can manage synapses within a projection, as well as send connections between the neurons to the backend and receive them from the backend.
