RelativePositionAssert class

Describes the relative position of a widget targeted by WidgetTrait.

Contrary to PositionAssert the positional information in here is relative to a specific subject defined with refersTo. Depending on the value of the field, the positional fields left, top, right and bottom are interpreted differently. Corresponding constructors are available for the different possibilities.
