How can I separate emails like in gmail, outlook, or on the iphone on commas?

Question

I am having my users type in multiple email addresses in one portion of my app. Every time they press comma or semicolon, I want that email to split off into an individual cell, kind of like tags in stack overflow:

I was wondering if their were any plugins or simple ways of acheiving this.
