Change ActionView ERB Handler from Erubis to Erubi
Erubi offers the following advantages for Rails:

* Works with ruby's --enable-frozen-string-literal option
* Has 88% smaller memory footprint
* Does no freedom patching (Erubis adds a method to Kernel)
* Has simpler internals (1 file, <150 lines of code)
* Has an open development model (Erubis doesn't have a
  public source control repository or bug tracker)
* Is not dead (Erubis hasn't been updated since 2011)

Erubi is a simplified fork of Erubis that contains just the
parts that are generally needed (which includes the parts
that Rails uses).  The only intentional difference in
behavior is that it does not include support for <%=== tags
for debug output.  That could be added to the ActionView ERB
handler if it is desired.

The Erubis template handler remains in a deprecated state
so that code that accesses it directly does not break.  It
can be removed after Rails 5.1.

= Action Pack -- From request to response

Action Pack is a framework for handling and responding to web requests. It
provides mechanisms for *routing* (mapping request URLs to actions), defining
*controllers* that implement actions, and generating responses by rendering
*views*, which are templates of various formats. In short, Action Pack
provides the view and controller layers in the MVC paradigm.

It consists of several modules:

* Action Dispatch, which parses information about the web request, handles
  routing as defined by the user, and does advanced processing related to HTTP
  such as MIME-type negotiation, decoding parameters in POST, PATCH, or PUT bodies,
  handling HTTP caching logic, cookies and sessions.

* Action Controller, which provides a base controller class that can be
  subclassed to implement filters and actions to handle requests. The result
  of an action is typically content generated from views.

With the Ruby on Rails framework, users only directly interface with the
Action Controller module. Necessary Action Dispatch functionality is activated
by default and Action View rendering is implicitly triggered by Action
Controller. However, these modules are designed to function on their own and
can be used outside of Rails.
