=head1 NAME
Dancer2::Template::TemplateToolkit - Template toolkit engine for Dancer2
=head1 VERSION
version 0.166001
=head1 SYNOPSIS
To use this engine, you may configure L<Dancer2> via C<config.yaml>:
template: "template_toolkit"
Or you may also change the rendering engine on a per-route basis by
setting it manually with C<set>:
# code code code
set template => 'template_toolkit';
=head1 DESCRIPTION
This template engine allows you to use L<Template::Toolkit> in L<Dancer2>.
=head1 METHODS
=head2 render($template, \%tokens)
Renders the template. The first arg is a filename for the template file
or a reference to a string that contains the template. The second arg
is a hashref for the tokens that you wish to pass to
