  Leak potassium current
  ----------------------

  This mechanism was written to be used as a potassium channel that is
  open or closed by neuromodulators.  

  WARNING: this current is NOT inserted as a standard current, but as a 
  point process (same way as a synapse or current injection).

  Procedure for insertion:

	objectvar kl
	kl = new kleak()

	access <compartment_name>
	kl.loc(0.5)

	kl.gmax = ...
