Browsers are becoming much more restrictive in loading content
in Iframes and many sites have also added code to prevent loading
in Iframes. None of the examples previously provided in the
default RTIR configuration were still working.

+The Iframe option for adding research tools to the lookup pages in RTIR
+previously configured with C<$RTIRIframeResearchToolConfig> has been removed.
+Browsers are becoming much more restrictive when loading content in Iframes

+Iframes. In our testing, the default example configurations provided with
+RTIR no longer worked and we didn't find other replacements that would
