This software is a computer program whose purpose is to outline the
track of a fault, to do perpendicular profiles to this track, stack them
and have the slip-curve plot as an output.

Dependencies
  python2.7
  gdal-bin
  python-gdal
  python-matplotlib
  python-qt4
  python-scipy

Usage
  Command:
    python fdsc.py

  Drawing the fault trace:
    draw: mouse left-click
    erase the last point: mouse middle-click
    save fault trace: mouse right-click

  Offsets tool:
    there are 4 points (<=> 2 line segments) 'framing' the offset
    to change a point's position: left-click on it and another left-click on the new position of the point
    the offset is computed between the 3rd and the 2nd point
    to save the offset: right-click
    all the offset values are saved into a file, as well as other information regarding the stacking parameters

  Slip-curve tool:
    plotting the offsets along the fault following column, line, parallel or perpendicular directions
      abscissa: distance along the fault
      ordinate: offset values
