Example
-------
``` javascript
Template.user.created = function() {
var tpl = this;
tpl.name = new ReactiveVar();
tpl.age = new ReactiveVar();
tpl.watch("name", function(value) {
console.log("The value of 'name' changed! It is now: " + value);
});
tpl.watchGroup(["name", "age"], function(values) {
console.log("The value of either 'name' or 'age' changed! Their new values are now the following.");
for (var k in values) {
console.log(k + ": " + values[k]);
})
});
}
```
