Added function that emulates the linspace function of matlab (creates an array of linearly spaced numbers with given bounds / size)
added function to generate the Schuh/Patala legend. Currently all of the image drawing is done with QtGUI components (QImage and QPainter). Any code with QtQUI dependancies has been commented out.
