Data plotting

## Introduction

KPlotWidget is a QWidget-derived class that provides a virtual base class

for easy data-plotting. The idea behind KPlotWidget is that you only have

to specify information in "data units"; i.e., the natural units of the

data being plotted.  KPlotWidget automatically converts everything

to screen pixel units.

KPlotWidget draws X and Y axes with tick marks and tick labels.  It

automatically determines how many tick marks to use and where they should

be, based on the data limits specified for the plot.  You change the limits

by calling `setLimits(double x1, double x2, double y1, double y2)`.

Data to be plotted are stored using the KPlotObject class.  KPlotObject

consists of a QList of QPointF's, each specifying the X,Y coordinates

of a data point.  KPlotObject also specifies the "type" of data to be

plotted (POINTS or CURVE or POLYGON or LABEL).
