Load Today's tasks only (Issue #13)

label: enhancement 
By definition, one only works on Today's tasks, right?

I have tons of tasks marked as Upcoming and Later, that I'm definitely not going to work on them soon, and they are loaded on Asana Time Track, making it a huge and uncontrollable list of tasks.

What do you thing about loading only My Tasks marked for Today? Does Asana API allow it?
