ReorderableFit<T extends Object> class

Placing children evenly on a screen with an ability to reorder them.

Layout depends on the provided axis.

left or right, top or bottom, width and height should be specified only if this ReorderableFit should take a portion of the screen. Otherwise, the whole available space will be occupied.
