What is a View Helper?
A View Helper is simply a class that follows particular naming conventions, When attached to a view object, you can call the helper as if it were a method of the view object itself. The View object retains helper instances, which means that they retain states between calls.
Common use cases for view helpers include:
* Accessing models
* Performing complex or repeatable display logic
* Manipulating and formatting model data
* Persisting data between view scripts
