/**
 * checkForSupportedSetting Handlebars helper
 * Takes a solutions registry entry and settingKey, then checks to see if
 * it's a setting that the solution supports. This is primarily used to see
 * if a generic preference setting is supported by the solution and used
 * in one of it's transformations.
 * The underlying functionality for this should be moved to a utility method
 * with unit tests.
 *
 * @param {Object} solution - The solution registry entry.
 * @param {String} settingKey - The generic pref setting key.
 * @return {Boolean} Returns `true` if this solution supports the setting, otherwise `false`.
