FAILURE: Build failed with an exception.

The onMeassure() step now finds the largest child when setting the wrapping dimension.

measureChild() now properly handles the case where all parent views are wrap_content. RecyclerView's own getChildMeasureSpec() has some limitations in this regaurd which we must work around.

The result is allowing RecyclerView to size it's self entirely based on it's children as well as deal with heterogenous children.
