I've started working on this... but have questions about how crazy we want to go with the E.164 conformance.
Playing with the [libphonumber demo](http://rawgit.com/googlei18n/libphonenumber/master/javascript/i18n/phonenumbers/demo-compiled.html), it seems to be much stricter than what E.164 requires. e.g., if I'm reading E.164, "+" is optional.
We can come up with a subset, like must start with "+", be at least 3 digits long, and have no more than 15 digits. And we canonicalize that by collapsing white space.
