Projection tool

In this Beta release, the projection tool provides simple stereographic projection of axis/lines, pole to planes, great circles and small circles.

These structural elements can be plotted using equal area or equal angle projections (Wulff or Schmidt canvas), in the upper ot lower hemisphere, using colors and five different symbols.

The orientation data are entered in a two columns grid. It is possible to plot a selection of data or all the data, and each new plot can replace the previous one or can be added to the current plot.
