working on sub nav for task cells
animating opacity of add time icon on cell expand, still toying with listeners to get it right, then will add subsequent animations for other icons
add time icon has a slight y translation animation now
happy with the staggering in the animation from add time to edit task icons
added trash and calendar icons to animation, feels ok, spacing of center icons looks a bit off but can fix later... need to make them animate out now
added fade out animation for icons, now need to fix bug with icons not toggling nav when height toggled
completed issue #10, the sub nav is animating in and out... spacing and animation time will probably need tweaking, but its working
