+ * Returns a validated options dictionary given some requirements.  If any of

+ *
+ * @param  options
+ *         An object, the options dictionary to validate.  It's not modified.
+ *         If it's null or otherwise falsey, an empty object is assumed.
+ * @param  requirements
+ *         An object whose keys are the expected keys in options.  Any key in
+ *         options that is not present in requirements is ignored.  Each value
+ *         in requirements is itself an object describing the requirements of
+ *         its key.  There are four optional keys in this object:
+ *           map: A function that's passed the value of the key in options.
+ *                map's return value is taken as the key's value in the final
+ *                validated options, is, and ok.  If map throws an exception
+ *                it's caught and discarded, and the key's value is its value in
+ *                options.
+ *           is:  An array containing any number of the typeof type names.  If
+ *                the key's value is none of these types, it fails validation.
+ *                Arrays, null and regexps are identified by the special type names
+ *                "array", "null", "regexp"; "object" will not match either.  No type
+ *                coercion is done.
+ *           ok:  A function that's passed the key's value.  If it returns
+ *                false, the value fails validation.
+ *           msg: If the key's value fails validation, an exception is thrown.
+ *                This string will be used as its message.  If undefined, a
+ *                generic message is used, unless is is defined, in which case
+ *                the message will state that the value needs to be one of the
+ *                given types.
+ * @return An object whose keys are those keys in requirements that are also in
+ *         options and whose values are the corresponding return values of map
+ *         or the corresponding values in options.  Note that any keys not
+ *         shared by both requirements and options are not in the returned
