defined Heaviside(0) as 0.5
adding extra parameters to variable mechanisms
undoing not-so-smart netbeans refactoring
associate extra pars with var vech; display them in the desc string
extra parameters for var mechs now exported to neuron
added info on var mech extra pars to full cell info string
Slight update to plotting of generic hdf5 data files; tested with HDF5 Neo file
