          return mergeFromTemplate(readResource(templatePath), values);

  <code>
  String result = Templator.mergeFromPath(readResource("/message_template.txt", valuesMap));
  </code>
  
  @param templatePath template to merge
  @param values values to merge into a template
  @return result of merging
