\brief A class which draws a coordinate grid
The QwtPlotGrid class can be used to draw a coordinate grid.
A coordinate grid consists of major and minor vertical
and horizontal gridlines. The locations of the gridlines
are determined by the X and Y scale divisions which can
be assigned with setXDiv() and setYDiv().
The draw() member draws the grid within a bounding
rectangle.
