=head1 Trog::Config

A thin wrapper around Config::Simple which reads the configuration from the appropriate place.

=head2 Trog::Config::get() = Config::Simple

Returns a configuration object that will be used by server.psgi, the data model and Routing modules.
Memoized, so you will need to HUP the children on config changes.
