As the doc, connect should return a bool.
So the line
https://github.com/pintsized/ledge/blob/2474cab721dc300b1dbc6ba40121283ba44bea47/lib/ledge.lua#L228
should be replaced by return driver, nil;
And the bool new() on the doc should be change.
While I return nil(return nil for no max) on get_max_size method, here will throw an error(attempt to compare nil with number).
