 Takes a path to a CGI from C<root/cgi-bin> such as C<foo/bar.cgi> and returns
-the action name it is registered as. See L</DESCRIPTION> for a discussion on how
-CGI actions are named.

-A path such as C<root/cgi-bin/hlagh/bar.cgi> will get the private path
-C<foo/CGI_hlagh__bar_cgi>, for controller Foo, with the C</>s converted to C<__>
-and prepended with C<CGI_>, as well as all non-word characters converted to
-C<_>s. This is because L<Catalyst> action names can't have non-word characters
-in them.

-This means that C<foo/bar.cgi> and C<foo__bar.cgi> for example will both map to
-the action C<CGI_foo__bar_cgi> so B<DON'T DO THAT>.
