DESCRIPTION
Base Template Store class which can be extended to provide an additional/different method to provide template content. This class is separate from the Provider class in order to supply a more simple API which consists of nothing but returning I/O associated with a template name. While this is the job of the original Template::Provider from the native Template::Toolkit, RapidApp::Template::Provider already extends the original concept beyond simple template fetching, which justifies the need for this additional layer.
