Minor wire_struct improvements:

* The concatenated value can be set with the special `kwarg` "_value". This is
  useful when the `wire_struct`'s class name is not known.

* Changes to make `wire_struct` instances documentable with Sphinx. The
  generated class copies its docstring from the decorated class (`__doc__`),
  and the generated class's name now matches the decorated class's name.
  Previously all `wire_struct` classes were named `_WireStruct`.

* Add a new `class_name` argument to `wire_matrix`. This lets users set the
  name of the generated class. This is optional for backwards compatibility,
  but highly recommended to help with debugging. Previously all `wire_matrix`
  classes were named `_WireMatrix`.
