This file contains an object which
calculates the current through a membrane, the reversal potential, and
the chord conductance of a single ionic species using the Goldman
Hodgkin Katz equation (constant field equation). Extensive
documentation may be found in "ghk.doc" and "ghklib/ghklib.g". This
object was submitted by Subbakrishna Shankar. (NOTE: This has since
been incororated into GENESIS 2.1, with some modifications.)
