make cyclic color map made by two colors
cmap = cmap_cycle(color_name,Ncycle,Nrepeat)
base_color : [N x 3] color map matrix
bg_color : [1 x 3] RGB color corresponding to background color
Ncycle : cycle length
if N < Ncycle, bg_color is added (Ncycle-N) times
if N >= Ncycle, base_color is trancated as [Ncycle x 3]
Nrepeat : repetition number of cycle
cmap : [(Ncycle*Nrepeat) x 3] color map matrix
