+ * argumentError(argument, message) -> TypeError
+ * - argument (Object): action with broken argument
+ * - message (String): error message
+ *
+ * Error format helper. An error from creating or using an argument
+ * (optional or positional). The string value of this exception
+ * is the message, augmented with information
+ * about the argument that caused it.
+ *
+ * #####Example
+ *
+ * var argumentErrorHelper = require('./argument/error');
+ * if (conflictOptionals.length > 0) {
+ * throw argumentErrorHelper(
+ * action,
+ * format('Conflicting option string(s): %s', conflictOptionals.join(', '))
