# This is a complete hack, and may even break the behavior of other parts of the app
# For the sitemap to function correctly, we need to have a list of all models
# That are sitemappable - so all models need to be loaded
# Rails does not actually require_dependency on the models though - so at the time
# of the plugin initialization, it seems like there are no subclasses to AR Base
# As a result, we require_dependency here on all of the models
# This is a hack because it only looks in the app models directories (and all subdirectories)
# However, a model could also live in a plugin
# The way this is set up, if I have a model in my models directory, and a model in my plugin
# that is sitemappable, if the sitemap is called _before_ the other model is called, the sitemap
# will not include the plugin's sitemap - so each plugin that implements a model with sitemappable
# also has to require_dependency on that model - a total and complete hack
# We do this before the routes so the routes can read from the index
