Iterable.toMap accepting both key and value mapper

[Artur Biesiadowski]

Any chance of adding following code to Iterator/IterableExtensions in one of future versions of xtend?

    public static <T, K, V> Map<K, V> toMap(Iterable<? extends T> values, Function1<? super T, K> computeKeys, Function1<? super T, V> computeValues) {
        return toMap(values.iterator(),computeKeys,computeValues);
    }
   
    public static <T, K, V> Map<K, V> toMap(Iterator<? extends T> values, Function1<? super T, K> computeKeys, Function1<? super T, V> computeValues) {
        if (computeKeys == null)
            throw new NullPointerException("computeKeys");
        if (computeValues == null)
            throw new NullPointerException("computeValues");
        Map<K, V> result = Maps.newLinkedHashMap();
        while(values.hasNext()) {
            T t = values.next();
            result.put(computeKeys.apply(t), computeValues.apply(t));
        }
        return result;
    }

Yes, that would be useful. 

Could you open a PR against https://github.com/eclipse/xtext-xtend ?

Thanks!

Wasn't as easy as I expected, due to CLA, sign-off footers and different project (xtend-lib rather than xtext-xtend), but hopefully it works now.
