Fix for bottom sheet fling/snap/settle bugs about custombottomsheetbehavior

[miguelhincapie]

I guess we are missing something in what he did in one of those commit related to fling.
Someone from my last company show me the app behavior in one smartphone with an old version of this library and the new one (he download my app from the market and that one has the last commit). In old one I tried like 12341234 times reproduce the issue related to "jump" anchor_point and get from collapsed to expanded in one shoot but I couldn't. Meanwhile in the news one was easy to reproduce it.
So I guess we are missing a little logic behind those changes.

Sorry - I am not clear on what the issue is. Are you saying the 'stop at anchor' worked BEFORE PR#27 and doesn't work AFTER PR#27?

[miguelhincapie]

In somehow yes, I mean, like I said, I tried so many times in an old version of the lib and I couldn't reproduce "jump state" behavior (It could be I didn't try in the right way... no idea). But what I'm sure is that was easy to reproduce it using last version of the lib, so I'm guessing we are missing some logic in the new fling behavior.

Can you take a look at my fork and see if everything works? I've made many changes over the past few days. If it works I can issue a PR.

My phone died unfortunatelly so I am stuck with the emulator for a couple of days , very clunky... :(

OK, I see the issue - I have my BottomSheet in a Horizontal ViewPager (another layer of NestedScrollingParent), so some of the code doesn't work the same in your lib demo. I am going to push out my Horizontal ViewPager code as a lib so you can take a look, and maybe you'll find use for the paging ability as well ... :)

[miguelhincapie]

yeah, because all the different configurations you can have with this lib, I'm going to make 2 or 3 demos plus the principal one. It sounds good having integration with that lib you are going to release.

note: I don't like how it sounds when you say "in your lib" :D. I mean, I just started this lib but it has grown because @akaN44 and you... so it's better if you say "our lib".

@miguelhincapie - Still working on a clean demo and fixing toolbar, but you can check out https://github.com/vit001/CustomBottomSheetBehavior - the paging and scrolling works perfrect for me.

By the way, if you don't want the horizontal pager functionality, you can always provide an adapter with only one item.
