Better docs

[lukef]

We need better documentation. We're working on it :)

Any progress on documentation guys? I am building an app avoiding usage of material widgets, so for routing need to use new WidgetsApp() in flutter as opposed to new MaterialApp() which makes routing a bit more verbose and cumbersome.

Decided to give Fluro a go, as it seems like a more clear implementation and supports params / transitions, but readme is not very descriptive. Examples help, but were a bit time consuming to figure out.

@iljadaderko it might be handy to know what specifically what you think would be useful so we can prioritize those items. Also, feel free to ask anything specific on stack overflow. We'll make sure that we answer quickly. In the meantime, we'll lay out some additional docs.

@lukef I jumped to your wiki section, it has 3 kinks that are currently not leading anywhere, but it looks like a good start. Personally, I'd love to see more detailed guide for animation implementation for route transitions, perhaps a more simple example i.e. no deep linking that then builds into complex one.

Guide on how to "nest routes", for example I want to display certain layout under /dashboard/**, but within that layout I'd also need to show different pages i.e. /dashboard/statistics.
