ChanHH implements a Hodgkin-Huxley form active ion Channel. The channel conductance G is equal to M^Mexp * H^Hexp, where M and H are functions of voltage and time, and Mexp and Hexp are constants (integer by convention, but any value is allowed here).

This is not an abstract base class; you can instantiate it, but it doesn't do much. The UpdateM and UpdateH methods do nothing, which means that the gating variables (M and H) stay wherever you set them. Subclasses should override these two functions.
