Fry point-to-point strain analysis plots

GeoFryPlots performs strain analyses using the Fry point-to-point method. Data can be either read in from an ascii file (as pairs of x,y coordinates) or can be digitised directly into a data window using the mouse. Bitmap images to be digitised can be loaded into the data window from file. Fry plots are displayed in a separate FryPlot window within which a best-fit strain ellipse to the plot can be constructed using the mouse.
