Support for different day based ranges

[YanivRan]

Right now the scheduler is hard set on a 4 weeks (in days) for display. It would be nice to have it more flexible. It would be nice to be able to send a start date, and end date and get a table that is showing the right range (right now it will distort the entire table).

Thanks for the feedback. Someone is actually working on this right now, though I'm not sure how long it will be. A PR is welcome, otherwise, it may be awhile. I'm pretty busy on things that are paying me right now. :)

Ok so @zackify guilted me into fixing this. :) As of 58b2280 the scheduler now supports this. It wasn't a big change at all. Version 0.2.0 has been released.

The scheduler will now accept whatever date range you give it, and will advance/retard the date range according to the number of days in date range you give it.
