An Injector is an ideal current source, that is, one which provides a
constant current regardless of the potential of the voltage sink to
which it is attached. Such a current source has an infinite internal
resistance, i.e. zero conductance, and an infinite source potential, so
that the current (E-V)G = EG-VG = EG for any finite V.
This is implemented by keeping G equal to 0, but letting EG return E
(as if G=1) -- a bit of a double standard. Additional methods SetI and
GetI are implemented to allow this class to be used in a more
technically correct manner.
