3.0.0-alpha3

• The BottomSheet() dialog behavior now accepts an optional LayoutMode parameter, which you can use
  to instruct the bottom sheet to be expandable to the screen height or limit itself to wrap the content
  of its content. See the updated Bottom Sheets documentation.
• Added a setPeekHeight(...) extension method for MaterialDialog that you can use to set the
  default peek height and animate peek height changes.
