The dispatchLoopStartup() function initializes the view and adds an additional view helper directory to it.
By default the view created by the ViewRenderer sets up two directories for the view helpers:
Zend/View/Helpers and the local module??™s views/helpers. Most applications have view helpers that are used
across multiple modules and Places is no exception.
