Accordion.prototype.filterLocale appears to be unused

[36degrees]

All references to filterLocale from within the class appear to have been removed in 4631b19 and there don't appear to be any other instances of it within alphagov.

govuk_publishing_components/app/assets/javascripts/govuk_publishing_components/components/accordion.js

Lines 117 to 124 in 656cee6

	GemAccordion.prototype.filterLocale = function (key) {
	if (this.$module.actions.locale && this.$module.actions.locale.indexOf('{') !== -1) {
	var locales = JSON.parse(this.$module.actions.locale)
	return locales[key]
	} else if (this.$module.actions.locale) {
	return this.$module.actions.locale
	}
	}

On this basis I think the function is unused can be removed.

Possibly also these lines:

govuk_publishing_components/app/assets/javascripts/govuk_publishing_components/components/accordion.js

Lines 21 to 23 in e0c5cad

	// language attribute pulled from data attributes
	this.$module.actions = {}
	this.$module.actions.locale = this.$module.getAttribute('data-locale')
