Add Iterables.compare()

[GoogleCodeExporter]

Currently there is usefull Iterables.elementsEqual(Iterable<?>, Iterable<?>) 
that checks for equality.
Consider adding
<E extends Comparable<? super E>> int Iterables.compare(Iterable<? extends E>, 
Iterable<? extends E>) that compares elements. Also, maybe a version with 
comparator too.

My usecase:
I'm writing a comparator for a class that have List<String> field and want to 
compare this fields.

What about Ordering.lexicographical() ?
Comparable version is doable via Ordering.natural().lexicographical(),
Comparator version via Ordering.from(yourComparator).lexicographical().
