documentation

The Insets class was added as an all purpose class holding the insets of a geometric
element like a view. A inset object just contains four dimensions specifying the top, left
right and bottom distance between the object and an outer border. Beside the simple methods
for setting and querying the instance variables, there also exists the methods for encoding
and decoding the inset as a literal array.
The insets class is used i.e. by the GridBagConstraints class.
