31The first seven colors are the same as Matlab's predefined
32values for the PLOT command, i.e.
33
34  'b','g','r','c','m','y','k'
35
36Syntax:  linecolor = colordg(n);
37
38Input: N , integer between 1 and 15, giving the following colors
39
40 1 BLUE
41 2 GREEN (pale)
42 3 RED
43 4 CYAN
44 5 MAGENTA (pale)
45 6 YELLOW (pale)
46 7 BLACK
47 8 TURQUOISE
48 9 GREEN (dark)
49 10 YELLOW (dark) 
50 11 ORANGE
51 12 MAGENTA (dark)
52 13 GREY
53 14 BROWN (pale)
54 15 BROWN (dark)
55
56Output: LINECOLOR  (1 x 3 RGB vector)
57
58Examples:
59  1)   h = line(x,y,'Color',colordg(11)); %Picks the orange color
60  2)   colordg demo  %Creates a figure displaying the 15 colors
61  3)   axes;  set(gca,'ColorOrder',(colordg(1:15)));
62       Overrides the default ColorOrder for the current axes only
63  4)   figure; set(gcf,'DefaultAxesColorOrder',(colordg(1:15)));
64       Overrides the default ColorOrder for all axes of the current
65      figure
66  5)   set(0,'DefaultAxesColorOrder',(colordg(1:15)));
67       Sets the default ColorOrder for all axes to be created during
68       the current matlab session. You may wish to insert this
69       command into your startup.m file.
