Add support for dynamic tutorials

Hi, I saw PR-80 was made a bit untimely, but I liked very much the setRectSupplierFromView() made by Oliver there.

Maybe it is possible to add some kind of a smart processing for shapes?

Hi! I added some more changes to the library. There are basically 4 things in this PR now.

• ability to let the library construct the shape based on the target's view (will provide a RoundedRectangle)
• ability to pass click to highlighted area while blocking all other regions of the overlay. It is also possible to just disable the clicking on the target throught the target builder
• ability to specify simple horizontal captions via target builder. The library will place them above or under the highlighted area according to the desired margins
• added some intermediary SpotlightCoordinator interface. Basically, it holds the current Spotlight instance. The main purpose is to be able to walk inside the app during the active Spotlight (by utilizing target clicking ability). There is a new example which demonstrates how 2 fragments may use this shared Spotlight instance. Their Activity is assigned the SpotlightCoordinator role

Hope that helps someone someday! Thanks.

@pratclot You should add code examples about how to achieve the abilities you've added in this PR.

@Nasib555 actually, there are two new Activities already. Please check if they work for you.

Have a great day!
