+  connect is a facade over connectAdvanced. It turns its args into a compatible
+  selectorFactory, which has the signature:
+
+    (dispatch, options) => (nextState, nextOwnProps) => nextFinalProps
+  
+  connect passes its args to connectAdvanced as options, which will in turn pass them to
+  selectorFactory each time a Connect component instance is instantiated or hot reloaded.
+
+  selectorFactory returns a final props selector from its mapStateToProps,
+  mapStateToPropsFactories, mapDispatchToProps, mapDispatchToPropsFactories, mergeProps,
+  mergePropsFactories, and pure args.
+
+  The resulting final props selector is called by the Connect component instance whenever
+  it receives new props or store state.
