 * Gets subtemplates for the default template or a given template file name

 * should contain snippets identying subtemplates, such as "input". The function
 * will then return the full path to dpdefault_info.tpl. If a non-default
 * template file is given, for example dpcustom.tpl, and the subtemplate for it
