Custom taxonomies UI as radio buttons


I'd like to suggest that, when you create a custom Taxonomy using CustomPress, you have the chance to set it the way that a user (when creating a new custom post) cannot choose more than one taxonomy value.

For instance. Imagine you have a property-listing site and a taxonomy called "price range" with values like 100k, 100-200k and 200K-up.

It has sense that the price cannot be in more than one range at a time.
