SDDRAWROC  Draw interactive ROC plot

    FH=SDDRAWROC(R,COLSTR)

 INPUT
    R       SDROC object
    COLSTR  cell array with color, line and marker strings (see PLOT)

 OUTPUT
    FH      figure handle

 FIGURE INTERACTION
    Cursor keys  Change performance measures
    w            show/hide operating point data (weights/threshold)
    s            save current op.point to a pipeline or algorithm
    f            fold info: Toggle between error bars and per-fold
                 realizations (only for multi-fold ROC, see SDCROSSVAL)

 DESCRIPTION
 SDDRAWROC plots an interactive 2D ROC plot. Moving the mouse, different
 operating points may be investiagted. Pressing the 'w' key toggles
 display of weights/threshold in the figure title. Different measure
 combination may be selected using the cursor keys.  Clicking on any
 operatin point makes it current (black).  Using 's' key, operating point
 may be saved back in Matlab workspace into existing ROC object, pipeline
 or SDALG algorithm.
