- Throw error message when items are added before groups.
- Made graphHeight automatic if height is defined AND if graphHeight is smaller than the center panel when height is defined as well.
- Added new verticalDrag event for internal use, allowing the vertical scrolling of the grid lines on drag.
- Fixed moving legend when postioned on the bottom and vertical dragging

* @constructor DataStep
* The class DataStep is an iterator for data for the lineGraph. You provide a start data point and an
* end data point. The class itself determines the best scale (step size) based on the
* provided start Date, end Date, and minimumStep.
*
* If minimumStep is provided, the step size is chosen as close as possible
* to the minimumStep but larger than minimumStep. If minimumStep is not
* provided, the scale is set to 1 DAY.
* The minimumStep should correspond with the onscreen size of about 6 characters
*
* Alternatively, you can set a scale by hand.
* After creation, you can initialize the class by executing first(). Then you
* can iterate from the start date to the end date via next(). You can check if
* the end date is reached with the function hasNext(). After each step, you can
* retrieve the current date via getCurrent().
* The DataStep has scales ranging from milliseconds, seconds, minutes, hours,
