Actual implementation of the generalized IntFire4 mechanism, called
	IntFire4r: intfire4r.mod
Hoc-file defining a network of IntFire4r cells: IF4rNetwork.hoc
Session files bringing up a little GUI for plotting model behavior in
4 different initial conditions:


After compilation of intfire4r.mod (mknrndll with PC and MAC,
nrnivmodl under linux) run IF4rFigures.hoc in NEURON. This will load
intfire4r cells and bring up a panel with four choices ++,+-,-+,-- and
three graphs. The first+/- indicates whether the model starts with a
positive (+) or negative (-) dm/dt, the second +/- indicates whether
the model starts above (+) or below (-) m=0. The graphs show the
currents e (E), i2 (I) and the membrane potential m (M).

For example running "++" will generate figures such as:
