setting up on new machine
Finally got something which reads and parses a .dat file and draws to a cairo_surface. Surface is then transfered
via a file and pixbuf to a GtkImage. The image is packed in a grid and loaded into a scrolled window. Should be possible to eliminate
the temp file step.
Removed the intermediate file. Image created from pixbuf from cairo_surface_t.
Removed development files
Added requirement for target value on command line and calculated some more data files.
