Overview

Class that finds ERb templates. Here is how it can be configured:

template_format

What format (C32, CCDA, etc) are we looking for. This will cause the TemplateHelper to look for template_name.template_format.erb

template_subdir

The sub directory where templates live. If none is provided, it will look for templates in the root of the template_directory

template_directory

The root directory to look in for templates. By default, it is in the template folder of this gem. It can be handy to provide a different directory if you want to use this class outside of the HDS gem
