util.isEmpty incorrectly reports Date object as "empty"

Line 75 in 6c54528

const isEmpty = (o) => typeof o === 'undefined'

The documentation states that lowerLimit and upperLimit of each axis type (x, y, y2) can be a "number or Date". Unfortunately, GraphConfig.validateInput uses the util.isEmpty helper which returns true for a Date object. Yet, if I set either the lowerLimit or upperLimit properties on an existing Graph instance then call reflowMultipleDatasets, it works just fine and doesn't complain.

I'm not sure how you want to determine what is at fault here. Perhaps util.isEmpty is not faulty and it should simply not be used when validating the axis limits. I'll let you all decide.
