def render_nested_liquid(liquid_template, context)
  parsed_template = Liquid::Template.parse(liquid_template)
  output = parsed_template.render(context)
  # output.scan(/^#{VariableStart}(.*)#{VariableEnd}$/) do |o|
    # return render_nested_liquid(o, context)
  # end
  output
end

#variable(markup) ⇒ Object

Determine if we’re able to call the method. If not we pass the call back to Liquid’s standard method

This is dependant on the Liquid.allowed_namespaces being set
