LineUpLiteVirtual

LineUpLiteVirtual is a variant of LineUpLite which renders the rows in a virtual fashion based on react-virtual. This allows to render 1000s of rows with ease since only the visible rows are actually rendered.

Besides the normal LineUpLite properties this components needs an additional estimatedSize which is the estimated pixel size of a row. Morever, one has to assign a dedicated height to the components, since it automatically fills the available space but doesn't enforce a minimum height.
