An isopotential compartment with a capacitance and membrane potential.
It has an intrinsic leak to restPotential which can be specified either as the total membrane resistance (by setting the leak option to "set resistance") or indirectly throught the time constant (with the "set time constant" option). In the second case, the leak is adjusted so that it gives the desired time constant, whatever the capacitance of the cell is.
Whenever a spike is received on the reset port, the potential is set to zero for a period spikeWidth and then to resetPotential.
The compartment accepts any number of conductance providing components which include spike response functions, membrane channels, conductance projections and synapse populations.
Compartments can be connected together with resistive wires to produce multi-compartmental cells. Such cells may also be constructed by starting with a geometry specification. (dec 01 - not ready yet).
