Clone is not defined svg-morpheus.js:231

[Gar]

I am trying to morph an svg

 var myIcons = new SVGMorpheus('#iconset')
 myIcons.to('icon1')

I am seeing the following error:

svg-morpheus.js:231 Uncaught ReferenceError: clone is not defined

I figured maybe this was jQuery's clone method you are trying to use so I included jQuery, but I am still having the same issue.

The clone method is in helpers.js.
