Firebase wrapper for use in Protractor tests.

Use this module as a drop-in replacement for the Firebase module.
This will add some new methods to your Firebase instances that are useful for interacting with Firebase inside your test code. The methods integrate seamlessly with the Web Driver Control Flow, so you can assume that their operation completes before the next statement in the control flow is executing.
Below is the list of the new methods. They all return a webdriver.promise.Promise that is resolved once the operation has been successfully completed:
$remove()- Wrapper for remove()
$set(value)- Wrapper for set()
$setWithPriority(value, priority)- Wrapper for setWithPriority()
$setPriority(priority)- Wrapper for setPriority()
$update(value)- Wrapper for update()
$push(value)- Wrapper for push(). The promise will be resolved with a Firebase reference for the generated location.
$value(waits)- Reads the data from the current location and returns a promise that will be resolved with the data. If
waitsit true, the promise will only be resolved once non null data has arrived.
$valueChange()- Resolves once the data from current location has changed. The promise will be resolved with the new value.
$waitForValue(predicate)- Calls the
predicatecallback whenever the value changes with the new value as an argument. Resolves once predicate returns true for the given value.
