Ability to swipe down to bottom to close.

[MattL-NZ]

Can we have the ability to completely close the bottom sheet when we swipe all the way to the bottom? Or alternatively selecting the area of the screen where the bottom sheet is not showing.

Currently it isn't the default behavior but you can still workaround it by setting the lower bound at 0.0.
I'm thinking to add this feature in the next release to completely dismiss on swipe down and maybe mimic the default modal bottom sheet.
