Demo app

[kibotu]

Hi, i've created a demo app while trying to testing your library.

i can't seem to get a few things right

• one is that with parallax scrolling i can't seem to get the collapsing toolbar offset right
• the bottom offset (bottom sheet is behind navigation bar)

any suggestions on how to tackle those issues would be highly appreciated

thanks for your library, it's probably the only solution i've found on the internet that goes in the right direction of supporting bottom sheet behaviour with collapsing toolbar layout

another thing, i've added a few more setters for half state and peek height
