# Installs hooks to insert MasterView changed-template reparsing
# into the Rails request dispatching handler in ActionController::Base.
# 
# Ensures that MasterView output files are always current while running a
# Rails application.  The <code>:rails_reparse_checking</code> option in the
# MasterView configuration should generally be enabled/disabled in conjunction 
# with Rails class load caching, which is normally off in a development environment 
# configuration.  
# 
# Requires that MasterView templates be parsed at application startup to properly 
# initialize the mechanism for detecting template changes after application startup.
