Dynamic Method Handling
This class handles dynamic methods through the method_missing method
#method_missing(name, *args, &block) ⇒ Object
Implements the method lookup chain. When you call a method that doesn’t exist, we:
1. Try to call the method on the current DOM context
2. Return an assigned variable of the same name
3. Call the method on the helper object
4. Call super

Instance Method Details
#helper_method(name, *args, &block) ⇒ Object
In order to not pollute our templates with helpers. prefixed everywhere we want to try to distinguish helpers that are almost always used as parameters to other methods such as path helpers and not add them as elements
