* First approach to improve accessiblity * Clear accessibleElements in addSubview: and willRemoveSubview: * Adjust comments and rename viewNode to node * Create new accessible elements if screen coordinates of view changes * Remove legacy clearing of accessibleElements * Performance improvements * Use bounds for screenFrame calculation and indexOfObjectIdentical: in indexOfAccessiblityElement: * Add ASDK_ACCESSIBILITY_DISABLE compiler flag to disable custom accessibility code in ASDK * No need to set a frame if a subnode view is an accessibility element and not layer backed
