A proof-of-concept Project Aiming at a sort of Neural Network
=============================================================

Let's start with creating a few neurons and connecting them with synapses.
>>> from cybertools.brain.neuron import Neuron, Synapsis
>>> n01 = Neuron()
>>> n02 = Neuron()
In the simple default implementation the neurons are connected automatically
when creating a synapsis:
>>> s0102 = Synapsis(n01, n02)
>>> n01.senders
[]
>>> n01.receivers == [s0102]
True
>>> n01.getState()
<State 0.0>
>>> n02.getState()
<State 0.0>
When we change the state of a neuron and notify it, all its receiver synapses
get triggered so that the receiver neurons' states are updated:
>>> from cybertools.brain.state import State
>>> n01.setState(State(1.0))
>>> n01.getState()
<State 1.0>
>>> n01.notify()
>>> n02.getState()
<State 1.0>
To allow for concurrent access to the brain by different clients
simultaneously, the changes to the neurons' states may be under the control of
a session:
>>> n01.setState(State())
>>> n02.setState(State())
>>> from cybertools.brain.session import Session
>>> session = Session()
>>> n01.setState(State(1.0), session)
>>> n01.getState()
<State 0.0>
>>> n01.getState(session)
<State 1.0>
>>> n01.notify(session)
>>> n02.getState()
<State 0.0>
>>> n02.getState(session)
<State 1.0>
