- Updating Noble 1962 model:
* Exposing the membrane potential to the top-level model;
* adding SED-ML for the paced and pacemaker variants of the model.
Using OpenCOR Snapshot release 2021-09-14.

// Property names in the dotted notation may have an array index, such
// as "a[0]", to identify an array element, literally, "object.a[0]".
// When a notation start with an array index, such as "[0].a", it
// specifies an array element of the root object (array),
// "object[0].a".
// This class also serves as a base class for other Wire classes,
// preparing a root object and converting a return value, so that
// sub-classes just can implement _getValue() and _setValue() called
// from getValue() and setValue() implemented by this calss.
