Consider a more friendly height/width value for CellMeasurer cell styles

[bvaughn]

A user submitted this Plnk demonstrating a problem where a row wasn't resizing correctly when measure was called. The fix (shown in this Plnk) was to set the cell's style with height: 'auto' so it could grow bigger than its initial measurement.

This isn't intuitive for users. I believe it should be possible for defaultCellRangeRenderer to set width or height to "auto" automatically when CellMeasurer is being used.

This feature, as described in the issue summary, would not be a good idea. Grid relies on forcing a width/height so that all cells in a given row/column share a consistent size. If we set "auto" they would all tight-fit and it would look back.

However we still need to handle the case where the measure callback is used after initial measurements. I think the thing to do might be to just-in-time set the height or width to "auto" before measuring...
