/**
 MDCTextControlAssistiveLabelViewLayout objects tell MDCAssistiveLabelViews where to position their
 assistive labels. Instantiating one of these classes is tantamount to calculating a layout.
 Instances of this class are applied to MDCAssistiveLabelViews when MDCTextControls apply their own
 layouts.
