I pointed someone at this example and they were confused by the
shared state example.  To help with their confusion I updated
the example to show both shared and internal component state.

There is an issue with the `IncrementGlobal` action that I've so
far been unable to sort out.  Upon first load, if you click the `Add`
button beneath the `Persistan Count` display then the `IncrementGlobal`
action seems to be dispatched twice on a single click.  Hopefully,
someone will be able to point out my, likely, very dumb error.

Adding a custom hook to track the global state eliminates the
double increment on first click issue and leads to all of the
reference tracking being in the GlobalCount module.

Also, this does not require the use of any odd concept within
the components themselves.

This reverts commit 03e7282.
