  files.each{|f| load f }
end

# dynamic list of files
use Aerogel::Reloader, ->(){ Dir.glob["*.rb"] } do |files|
  files.each{|f| load f}
end

# named groups of files
use Aerogel::Reloader, "routes/*.rb", group: :routes do |files|
    files.each{|f| load f }
end

# adding observer on a named group
