Detailed Description

Base class for all objects to simulate.

SimObject defines the interface for all simulation objects.

The methods reset(), adjust() and advance() define the implemented model.

The methods nSpikeInputPorts(), SpikeOutputPorts(), nAnalogInputPorts(), nAnalogOutputPorts() , outputPortType, inputPortType define the input and outputs.

At the beginning of a simulation (at time $t=0$ ) reset() is called. For each time step (of fixed length $\Delta t$ ) during the simulation advance() will be called for each object and it is assumed that during the call to advance() the object calculates its next state.
