Fix for “CFS is not defined” console error.

When I add form like this https://mgibbs189.github.io/custom-field-suite/api/form.html I always get “CFS is not defined” error in console. After investigating back-end editing form, I found out that CFS()->form->load_assets(); is not adding one important piece of JS code on the front-end.
So, in order to fix this issue, add this JS code before the form:

<script>
var CFS = CFS || {};
CFS['get_field_value'] = {};
CFS['loop_buffer'] = [];
</script>

Final PHP code example:

CFS()->form->load_assets();
echo '<script>var CFS = CFS || {};CFS["get_field_value"] = {};CFS["loop_buffer"] = [];</script>';
echo CFS()->form( array(
// your args...
) );

Feel free to inject that JS on the page whichever way you want, just add it before form renders.
