Schedule Repeating Actions
==========================

Every now and then you reach the point where you need some part of your code to be called 
continuously at a certain interval. May it be every second, 24 hours or two months.

For this, MVI contain the `call_every` decorator that can be used as such::

    from mvi.mvi import MviService

    mvi = MviService()

    @mvi.call_every(seconds=60)
    def heartbeat():
        # do something every minute

    mvi.run()

By using this decorator, MVI will take care of calling your decorated fuction at the specified interval. 
Note that the decorated function are not allowed to take any arguments. `functools.partial` may be used to 
adhere to this requirement.
