#mediaCheck
This is a simple wrapper around matchMedia to run code on entry and exit from media queries. It also uses browser resize as a fallback for browsers that don't support matchMedia.
##Demo There is a really basic example here: http://sparkbox.github.com/mediaCheck/
##Example:
mediaCheck({
media: '(max-width: 420px)',
entry: function() {
console.log('starting 420');
},
exit: function() {
console.log('leaving 420');
}
});
