Initializes a registry of view paths for the various themes in our apps.

view_path_registry.rb

# this is an initializer and used to set up various themes
# so we can use the same instances on each request
# I'm wondering if $path_set_registry should be a 
# constant instead of a global variable

$path_set_registry = {}
Dir.entries('app/views/site_overrides').reject{|e| e.in?(['.', '..'])}.each do|domain|
  paths = ["app/views/site_overrides/#{domain}"]
  $path_set_registry[domain] = ActionView::PathSet.new(paths)
end
