Summary: additional package dynamics

Initial Comment:
The dynamic package does not work properly. The commands orbits, evolution, staircase and chaosgame etc do not accept any opctions 
including the ones used in the documentation. The problems is that the way os passing the options to plot2d fails. I include some examples:

(%i12) evolution(cos(y), 2, 11, [yaxislabel, "y"], [xaxislabel,"n"]);
Unknown plot option specified:  yaxislabel
#0: evolution(fun=cos(y),initial=2,n=11,options=[[yaxislabel,"y"],[xaxislabel,"n"]])(dynamics.mac line 54)
 -- an error.  To debug this try debugmode(true);

Unknown plot option specified:  real
#0: staircase(fun=cos(y),initial=1,n=11,options=[[real,0,1.2]])(dynamics.mac line 96)
 -- an error.  To debug this try debugmode(true);

(%i14) orbits(x+y^2, 0, 100, 400, [x,-1,-1.53,-0.001], [pointsize,0.9],[ycenter,-1.2], [yradius,0.4]);
Graph passed to plot2d...
Unknown plot option specified:  pointsize
#0: orbits(f=y^2+x,y0=0,n1=100,n2=400,domain=[x,-1,-1.53,-0.001],options=[[pointsize,0.9],[ycenter,-1.2],[yradius,0.4]])(dynamics.mac line 367)
 -- an error.  To debug this try debugmode(true);

(%i15) chaosgame([[0, 0], [1, 0], [0.5, sqrt(3)/2]], [0.1, 0.1], 1/2,
30000, [pointsize,0.7]);
Unknown plot option specified:  pointsize
#0: chaosgame(point=[[0,0],[1,0],[0.5,0.86602540378444]],p0=[0.1,0.1],b=0.5,n=30000,options=[[pointsize,0.7]])(dynamics.mac line 195)
 -- an error.  To debug this try debugmode(true);
