Add Iterables#fromEnumeration()

[GoogleCodeExporter]

It would be very useful for the Iterables class to have a utility to
convert an Enumeration into an Iterable.  This would allow Enumerations to
be used in the enhanced for loop:

Enumeration<T> e = ...;

for (T item : Iterables.fromEnumeration(e) {
 // Do something with item
}

But an Iterable can be iterated many times. An Iterable that threw 
IllegalStateException at the second iteration would be clumsy, clearly it's the 
wrong 
type for something like that.

We won't add such a method to the library, for the reason Jim mentioned.

Since it's possible some readers aren't aware, I'll add that we do have an
Iterators.forEnumeration() method, which adapts Enumeration to the appropriate 
type.

Fair enough, thanks for your time.
